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.
In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
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?
Module descriptors are now module.desc, no configuration allowed inside.
Module config files are <modulename>.conf, installed in
share/calamares/modules.
settings.conf is read from /etc/calamares, then share/calamares, and if
running with --debug also in the current dir.
Module config files are read from /etc/calamares/modules, then
share/calamares/modules, and if running with --debug also in
src/modules/<modulename> relative to the current dir.
