- This will leave /etc/{plinth,freedombox} empty by default making service more
robust to run across various environments and situations. See systemd's
explanation for more details.
- Use Debian maintainer scripts remove all the existing files in
/etc/plinth/modules-enabled.
- Read from /usr/share/freedombox/modules-enabled then from
/etc/plinth/modules-enabled and finally from /etc/freedombox/modules-enabled.
Later read ones override previously read files. Any file pointing to /dev/null
will mean the module must be ignored.
Tests:
- Clean up /etc/plinth, /etc/freedombox and
/usr/share/freedombox/modules-enabled. Run service and notice that files are
getting loaded from development folder using a debug message.
- Run setup.py and notice that files get installed in
/usr/share/freedombox/modules-enabled/ and in the next run they get loaded from
there.
- Create a override file in /etc/plinth/modules-enabled/transmission and notice
that overriden file gets priority over the one in
/usr/share/freedombox/modules-enabled.
- Link the file /etc/plinth/modules-enabled/transmission to /dev/null and notice
that is not loaded.
- Create another file in /etc/freedombox/modules-enabled/transmission and notice
that it overrides the previous two files.
- All affected modules are loaded.
- Build a new Debian package and ensure that upgrading 23.8 to new version
removes are all configuration files.
- Build developer documentation and test that Tutorial -> Full Code and Tutorial
-> Skeleton sections have been updated with references to
-.../modules-enabled/... paths.
- Install quassel and notice that certificates were copied to /var/lib/quassel
directory. Change domain to another domain and notice that certificates were
copied again to that directory.

- Remove freedombox-udiskie.service file. Don't run udiskie anymore. Use our own
implementation of auto-mounting.
- Schedule disk failure checking to 3 seconds after application initialization.
Also perform auto-mounting at that time.
- Listen to new filesystems added and auto-mount them.
- Listen to disk failing attribute and report to user via a notification.
- Add rules to polkit-1 to allow plinth user to mount drives.
- Add simple abstractions over DBusProxy objects make accessing properties
simpler.
- Replicate udiskie's approach to mounting disks.
- Mount as root user for now using command line instead of DBus API. This is to
keep compatibility with older code that mounted under /media/root with relaxed
permissions.
Udiskie analysis:
- On device added, media added, perform auto_add
- On device changed and is addable and old state is not addable or removeable
- Automount condition:
- Matches configuration
- Not ignored
- is_filesystem and not mounted -> mount
- crypto device -> try unlock -> if success, mount
- is partition table
- Get all non-ignored devices, if partition then mount
- Mount condition:
- Is not ignored
- Is filesystem
- Find device with path
- Get options from configuration
- Is ntfs and executable ntfs-3g is not available
- Call mount
- No support for udisks1
- Built-in rules
- {'symlinks': '/dev/mapper/docker-*', 'ignore': True}
- {'symlinks': '/dev/disk/by-id/dm-name-docker-*', 'ignore': True}
- {'is_loop': True, 'is_ignored': False, 'loop_file': '/*', 'ignore': False}
- {'is_block': False, 'ignore': True}
- {'is_external': False, 'is_toplevel': True, 'ignore': True}
- {'is_ignored': True, 'ignore': True}
Tests performed:
- Create a CDROM in VM, inject media. Disk should get mounted.
- Create a temp file. mkfs.ext4 it at top level. losetup it. It should not get
auto mounted as it is a top level internal device.
- Create a temp file. Create two partitions and format the partitions. kpartx
-a on it. Both the file systems should get mounted.
- Create a temp file. luksformat it. Create a filesystem. luksopen the file.
It should get auto mounted.
- Checking for disk space repeatedly happens every 3 minutes.
- Drives are checked for healthy status only once, 3 seconds after FreedomBox is started.
- FreedomBox is able to mount disks while running as 'plinth' user with
policykit-1 version 0.105-26.
- FreedomBox is able to mount disks while running as 'plinth' user with
policykit-1 version 0.116-2 from experimental.
- Temporarily flip the is_failing condition in report_failing_drive. When
FreedomBox is restarted, notification about drives failing show up. When the
condition is reverted to normal, the notification is withdrawn.
- Build new Debian package and upgrade system with 20.8 installed. Two files
should be removed:
/var/lib/systemd/deb-systemd-helper-enabled/freedombox-udiskie.service.dsh-also
/etc/systemd/system/multi-user.target.wants/freedombox-udiskie.service .
systemctl status freedombox-udiskie.service should report no such unit.

None of the files are installed into /etc/. They will unconditionally override
older versions of themselves. They are not likely to cause any configuration
file prompts.
