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.
- Make explicit which one runs in the host, which one is selectable.
- Document *location* parameter in the selectable version.
- Tidy up alignment of apidox.
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
The module preserves the extended attributes at rsync and the overlay
filesystem stores extended attributes by inodes.
The overlay filesystem keeps traces of the lower directory by encoding
and storing its UUID to the attribute trusted.overlay.origin. If the
index feature is on, that attribute is compared to the UUID of the lower
directory at every subsequent mounts and causes mount to fail with
ESTATE if it does not match.
This filters the namespace trusted.overlay.* by using the rsync option
--filter='-x trusted.overlay.*' to make sure the overlays extended
attributes are not preserved.
Fixes:
# mount -t overlay -o lowerdir=...,upperdir,...,workdir= overlay /mnt/etc
mount: /var/mnt/etc: mount(2) system call failed: Stale file handle.
# dmesg
(...)
overlayfs: "xino" feature enabled using 32 upper inode bits.
overlayfs: failed to verify origin (/etc, ino=524292, err=-116)
overlayfs: failed to verify upper root origin
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.
