fix tests to run also when swap present

Parsing the output from lsof had possibilities for race conditions.
Either due to short lived processes or issuing "tomb ps" from a terminal which cwd is from inside the tomb.
This would spit out available users on the system.
To avoid this use the lsof output directly.

In the future formatting could be reintroduced via commands like
"lsof +D "$tombmount" -F Lc" or "lsof +D "$tombmount" -F Lc0".

This fixes #503

 # Tomb ChangeLog
 
+## 2.10
+### Sep 2023
+
+This release adds optional support for Argon2 KDF brute-force
+protection and introduces support for doas as an alternative to sudo
+for privilege escalation. It also improves support for BTRFS formatted
+Tombs, adds zram detection as swap memory, updates documentation and
+translations and cleans up the script code.
+
+## 2.9
+### Jan 2021
+
+This release fixes all bugs introduced by the unfortunate 2.8 release
+series in 2020 as well introduces support for BTRFS formatted
+Tombs. The fixes are for password insertion to work on all desktops,
+as well the fix to a regression when using old Zsh versions. The new
+feature is activated by the '--filesystem' flag on 'lock' commands.
+It only supports BTRFS as internal filesystem of a Tomb instead of the
+default EXT4; resizing works as well to create and send or receive
+subvolumes and snapshots inside a Tomb. There are also some cleanups,
+small error handling improvements and no more need for suid actions by
+'forge' and 'dig' commands.

-# What is Tomb, the crypto undertaker?
-
-Tomb aims to be a free and open source system for easy encryption and
-backup of personal files, written in code that is easy to review and
-links well reliable GNU/Linux components.
-
-Tomb's ambition is to improve safety by way of:
-
-- a minimalist design consisting in small and well readable code
-- facilitation of good practices, i.e: key/storage physical separation
-- adoption of a few standard and well tested implementations.
-
-At present, Tomb consists of a simple shell script (Zsh) using
-standard filesystem tools (GNU) and the cryptographic API of the Linux
-kernel (cryptsetup and LUKS). Tomb can also produce machine parsable
-output to facilitate its use inside graphical applications.

-# What is this for, exactly?
-
-This tool can be used to dig .tomb files (LUKS volumes), forge keys
-protected by a password (GnuPG encryption) and use the keys to lock
-the tombs. Tombs are like single files whose contents are inaccessible
-in the absence of the key they were locked with and its password.
-
-Once open, the tombs are just like normal folders and can contain
-different files, plus they offer advanced functionalities like bind
-and execution hooks and fast search, or they can be slammed close even
-if busy. Keys can be stored on separate media like USB sticks, NFC,
-on-line SSH servers or bluetooth devices to make the transport of data
-safer: one always needs both the tomb and the key, plus its password,
-to access it.
-
-The tomb script takes care of several details to improve user's
-behaviour and the security of tombs in everyday usage: protects the
-typing of passwords from keyloggers, facilitates hiding keys inside
-images, indexes and search a tomb's contents, mounts directories in
-place, lists open tombs and selectively closes them, warns the user
-about free space and last time usage, etc.
-
-# How secure is this?
-
-Death is the only sure thing in life. That said, Tomb is a pretty
-secure tool especially because it is kept minimal, its source is
-always open to review (even when installed) and its code is easy to
-read with a bit of shell script knowledge.
-
-All encryption tools being used in Tomb are included as default in
-many GNU/Linux operating systems and therefore are regularly peer
-reviewed: we don't add anything else to them really, just a layer of
-usability.
-
-The file [KNOWN_BUGS.md](KNOWN_BUGS.md) contains some notes on known
-vulnerabilities and threat model analysis.
-
-In absence or malfunction of the Tomb script it is always possible to
-access the contents of a Tomb only using a dm-crypt enabled Linux
-kernel, cryptsetup, GnuPG and any shell interpreter issuing the
-following commands as root:
-```
-lo=$(losetup -f)
-losetup -f secret.tomb
-pass="$(gpg -d secret.key)"
-echo -n -e "$pass" | cryptsetup --key-file - luksOpen $lo secret
-mount /dev/mapper/secret /mnt
-unset pass
-```
-One can change the last argument `/mnt` to where the Tomb has to be
-mounted and made accessible. To close the tomb then use:
-```
-umount /mnt
-cryptsetup luksClose /dev/mapper/secret
-```
-
-# Stage of development
-
-Tomb is an evolution of the 'mknest' tool developed for the
-[dyne:bolic](http://www.dynebolic.org) 100% Free GNU/Linux
-distribution in 2001: its 'nesting' mechanism allowed the liveCD users
-to encrypt and make persistent home directories. Since then the same
-shell routines kept being maintained and used for dyne:bolic until
-2007, when they were ported to work on more GNU/Linux distributions.
-
-As of today, Tomb is a very stable tool also used in mission critical
-situations by a number of activists in dangerous zones. It has been
-reviewed by forensics analysts and it can be considered safe for
-adoption where the integrity of information stored depends on the
-user's behaviour and the strength of a standard AES-256 (XTS plain)
-encryption algorithm (current default) or, at one's option, other
-equivalent standards supported by the Linux kernel.
-
-## Compatibility

-## Compliancy
-
-Tomb qualifies as sound for use on information rated as "top secret"
-when used on an underlying stack of carefully reviewed hardware
-(random number generator and other components) and software (Linux
-kernel build, crypto modules, device manager, compiler used to built,
-shell interpreter and packaged dependencies).
-
-Tomb volumes are fully compliant with the FIPS 197 advanced encryption
-standard published by NIST and with the following industry standards:
-
-- Information technology -- Security techniques -- Encryption algorithms
-	- [ISO/IEC 18033-1:2015](http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=54530)  -- Part 1: General
-	- [ISO/IEC 18033-3:2010](http://www.iso.org/iso/home/store/catalogue_ics/catalogue_detail_ics.htm?csnumber=54531) -- Part 3: Block ciphers
-
-Tomb implementation is known to address at least partially issues raised in:
-
-- Information technology -- Security techniques -- Key management
-	- [ISO/IEC 11770-1:2010](http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=53456)  -- Part 1: Framework
-	- [ISO/IEC 11770-2:2008](http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=46370)  -- Part 2: Mechanisms using symmetric techniques
-- [ISO/IEC 27005:2011](http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=56742) Information technology -- Security techniques -- Information security risk management
-- [ISO/IEC 24759:2014](http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=59142) Information technology -- Security techniques -- Test requirements for cryptographic modules

-Any help on further verification of compliancy is very welcome, as the
-access to ISO/IEC document is limited due to its expensive nature.
-
-
-# Use stable releases in production!
-
-Anyone planning to use Tomb to store and access secrets should not use
-the latest development version in Git, but use instead the .tar.gz
-release on https://files.dyne.org/tomb . The stable version will
-always ensure backward compatibility with older tombs: we make sure it
-creates sane tombs and keys by running various tests before releasing
-it. The development version in Git might introduce sudden bugs and is
-not guaranteed to produce backward- or forward-compatible tombs and keys.
-The development version in Git should be used to report bugs, test new
-features and develop patches.
-
-So be warned: do not use the latest Git version in production
-environments, but use a stable release versioned and packed as
-tarball on https://files.dyne.org/tomb

+# Portable Tomb :: the crypto undertaker runs everywhere
+
+ [![continuous integration tests badge](https://github.com/dyne/tomb/actions/workflows/portable.yml/badge.svg)](https://github.com/dyne/Tomb/actions) test coverage status for portability
+ 
+## ⚠️ WORK IN PROGRESS 🛠️
+
+This is the portable version of [Tomb](https://github.com/dyne/tomb)
+
+[![software by Dyne.org](https://files.dyne.org/software_by_dyne.png)](http://www.dyne.org)
+
+# Purpose
+
+Portable tomb achieves direct **interoperable access to tomb volumes** between:
+
+- GNU base Linux (Ubuntu)
+- Busybox based Linux (Alpine)
+- MS/Windows using WSL2 (Ubuntu)
+- FreeBSD (WIP using libluksde)
+- ~~Apple/OSX using [MacFUSE](https://osxfuse.github.io/)~~
+
+After some extensive testing during 2022, __adoption of Veracrypt in portable Tomb has been dropped__ because of unreliability and bad performance.
+
+Portable tomb stays as an experimental branch that aims to reduce dependencies and in particular uses only the **POSIX sh interpreter**.
+
+# Status
+
+Portable tomb development is in progress and tracked via issues and the [portable milestone](https://github.com/dyne/Tomb/milestone/9).
+
+## Features
+
+The following features will be implemented where possible:
+
+- mount bind (Linux only)
+- ps / slam
+- resize (pending investigation)
+- index & search ([recoll based](https://github.com/dyne/Tomb/issues/211))
+- bury / exhume
+
+## Dependencies
+
+- FreeBSD: `fusefs-libs3 fusefs-lkl e2fsprogs util-linux libluksde`
+- Linux: `fuse3 util-linux`
+- crossplatform [Veracrypt binaries](https://files.dyne.org/tomb3/third-party) console-only
+
+## Note on Veracrypt
+
+The way upstream developers distribute Veracrypt is far from meeting our minimalist needs, but the console-only binary once installed has a few library dependencies and is all what we need.
+
+I setup [my own build](https://github.com/jaromil/veracrypt) and provide binary builds of Veracrypt v1.25.9 for download on Tomb's file repository for testing purposes.

+#    $BASH_LINENO, then
+# 4. Call the DEBUG trap handler again, but with $BASH_LINENO set to 1, then
+# 5. Call the EXIT trap handler, with $BASH_LINENO set to 1.

+# TRANSLATIONS
+## 1. How to translate
+Tomb uses the [Weblate](https://hosted.weblate.org/projects/tomb/tomb/) platform to manage the translation efforts of it's user community.
+
+In Weblate, an user can click "Start new translation", choose a language and click "Request new translation". Additionally, just to reinforce your request, we recommend opening an [issue](https://github.com/dyne/Tomb/issues/new) requesting the development team to open a new translation for your language.
+
+## 2. About files in this folder
+All translation files in this folder (those with a ".po" extension) are based on the `tomb.pot` file.
+
+POT files are just templates and they don't contain any translations. To do a translation, create a new PO file based on the template.
+
+The `tomb.pot` template must be created using the perl script `generate_translatable_strings.pl` **for each new version of Tomb**:
+
+```sh
+$ perl generate_translatable_strings.pl > tomb.pot
+```
+
+After that, just open the `tomb.pot` file in the [poedit](https://poedit.net/) program, and click on "Start new translation" (bottom left button), select your language, save and start translating.
+
+## 3. Updating translation
+In your favorite shell, make a backup of old file adding it's version, then update with `msgmerge`:
+
+```sh
+$ msgmerge --update <language>.po tomb.pot
+```
+
+Open the new updated PO translation file and start reviewing the translation. Poedit will highlight what has changed and what needs revision.
