Don't run xdg-icon-resource and update-desktop-database in the basic
setup for KDM. These tools have absolutely nothing to do with KDM. KDM
does not ship any icons in the hicolor theme, nor a .desktop file (let
alone one that handles any MIME type, the only case in which
update-desktop-database is needed).
I know the original shell script from Manjaro called these when setting
up KDM, but this is really the wrong place. If you need to call these,
they need to go into another module, and you also have to call them
independently of the selected display manager.
The default session setting in GDM is per user. Therefore, it is not of
much use to set it for the gdm user. (Nobody will log in as "gdm".)
Unfortunately, there seems to be no systemwide setting for the default
session, the AccountsService provides no such setting, and GDM just
hardcodes the fallback to use if it is not set in the AccountsService.
(GDM first tries "gnome", and if that is not available, it picks the
first session in the alphabet.)
Therefore, the best we can do right now is to set the default session
for the autoLoginUser. This is the case where it matters the most
anyway. We would also need the username of a non-autologin user in the
global storage to do any better.
Remove the hack that symlinks /usr/lib/lightdm/lightdm/gdmflexiserver as
/usr/bin/gdmflexiserver.
Upstream LightDM removed their gdmflexiserver implementation in 1.9.4 in
2013:
http://bazaar.launchpad.net/~lightdm-team/lightdm/trunk/revision/1841
In addition, LightDM was already adding the path containing its
gdmflexiserver implementation to PATH, so there was no use symlinking it
into /usr/bin, potentially overwriting the original version from GDM.
This must have been a workaround for an ancient LightDM version that
didn't even do that.
And finally, the hardcoded /usr/lib/lightdm/lightdm/gdmflexiserver path
was wrong on Fedora to begin with (we had used
/usr/libexec/lightdm/gdmflexiserver, but now the file is completely gone
because upstream removed it).
If a display manager is in the list, but not installed, do not return an
error message, but only print a debugging message and proceed.
This allows distributions that support multiple display managers to list
them all, independently of what the concrete live image will be using.
It turns out that I had messed this up. Issue #173 was addressed anyway
by the followup fix to unpackfs to only exclude the directories that are
actually mounted (which does work), but with this fix, /run is now
handled as intended.
PS: Should the mount job not check the return value of
libcalamares.utils.mount instead of failing silently?
Do not use a YAML list when only a single entry actually works. (It was
just silently using the last one.)
Create the default_desktop_environment DesktopEnvironment tuple. Before,
the setting was silently ignored altogether.
This reverts commit 9c799b32e9.
This was already right before. default_desktop_environment.desktop_file is not a
variable, it's a field of a variable. This commit is not valid Python:
"SyntaxError: invalid syntax".
The module creates /etc/machine-id and/or /var/lib/dbus/machine-id. By
default, it is enabled and creates both files, making the latter a
symlink to the former.
Add the following flags to rsync:
* `-H, --hard-links preserve hard links`
* `-A, --acls preserve ACLs (implies --perms)`
* `-X, --xattrs preserve extended attributes`
(i.e., the preservation options not already implied by -a).
Also exclude the special paths that do not make sense to rsync, because
reading the extended attributes from those can cause errors, at least
with SELinux enabled.
This fixes installation of Fedora systems with SELinux enabled.
