This is the bugfix part (rather than the "clean up this widgets mess")
of issue-1573, ensuring that the LookAndFeelPackage setting is
saved to the target system config file.
- Need to update the variant that is in use, **and**
explicitly update it in the widget, in order to re-load
the keyboard image for the newly-selected layout+variant.
The lookandfeeltool does not (always?) write the LookAndFeelPackage
key that the KCM does -- and which this module reads on startup
to find the default LnF. This seems to be a regression in recent
lookandfeeltool versions (or in the KCM code that backs it).
Workaround supplied by jghodd.
Fixes#1573
Previously, the auxerror information was never stored, and
the messages were all un-numbered or un-explained.
Now, consume that information and store it when check()
is called, ready to be used when (possibly much later,
or after a translation change) explanation() is called.
Mount guesses the filesystem if it is unset or if it is set to auto,
thanks to blkid. That is the case for the bind mountpoints like /dev or
/run/udev in mount.conf. See `mount(8)` for more details.
The drop-down of zones was initially unfiltered, so you could start
in Europe/Amsterdam and the zones drop-down would also show Australian
zones; picking Perth would have weird effects, since Europe/Perth
doesn't exist and so you'd end up in New York instead.
- set the filtering region immediately, rather than only when the
region changes.
Various file writes were not being checked, and the code
was a bit tangled; specifically keyboardq did **not**
configure properly on KaOS and now seems ok.
The root mount-point can end with a / while the mount-point read from
the file /etc/mtab does not end with a /.
This leads to skip the unmounting of the root mount-point and causes the
removal of the root mountpoint directory to fail with EBUSY because it
is still mounted.
This uses the python functions os.path.normpath() to normalize the root
mount-point (i.e. to drop the trailing /) and os.path.commonprefix() to
determine the longest common prefix between the two mount-points. If the
returned prefix is identical to the normalized root mount-point then the
mount-point must be added to the list of the mount-points to unmount.
More generally, the python modules should rely on the os.path functions
to compare for paths instead of using strings. It covers this way lots
of corner cases (path with "//", "/../", "/./", ...).
