mount: Remember the extraMounts (and extraMountsEfi, if applicable) in
the global storage (as "extraMounts").
unpackfs: Read the extra mounts from the global storage to generate the
exclude list instead of trying to detect it from the "mount" command's
output, because the latter also includes normally-mounted destination
partitions.
This makes having separate partitions for non-/ mountpoints work again.
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.
