RFC: Blivet & mounting

Hello, OpenLMI project uses Blivet, former Anaconda storage library, to manage storage. Management of storage also means management of mounts, i.e. ability to mount/unmount/remount stuff, list existing mounts and add/delete/modify/list entries in /etc/fstab. The installer somehow manipulates fstab and mounts stuff and there is some code in Blivet for that, but I am not sure it can be easily extended for generic use case. Is generic mounting/unmounting capability that something Blivet should do, so it would be integrated there, or there should be separate library for this? In both cases, we (=OpenLMI) would /probably/ provide the code. Is there any other potential Blivet user who needs mounting? Can the installer benefit from more generic mounting? What OpenLMI needs: - parse /proc/mounts and provide list of mounts with their options - parse /etc/fstab and provide list of persistent mounts with their options (which can be different to /proc/mounts, someone might re-mount something with different options!) - re-mount a mount with different options - create new mount, both permanent (with fstab entry) and 'temporary' - unmount anything (incl. removing entry from fstab). BTW, for fstab manipulation I am thinking about augeas-python. It does not pull any big dependency except libxml2, still it's yet another package needed in installer ramdisk if generic mounting is in Blivet. Jan
