[lxc-devel] loop mounts and #195

[Wolfgang Bumiller]

We came across lxc's #195 while working on our frontend to support
mount entries via lxc.mount.entry.

The issue there (despite the change of the title) seems to be just the
`loop' option (which ends up passed to mount(2) as part of the
`data').

There's already code for loop devices, and a loop 'bdev' type for a
`loop:` prefixed rootfs, so adding support for loop mounts shouldn't
be all too hard (I'm willing to work on that.)

I'm also wondering, however, if the use of libmount has been considered
before? Admittedly I haven't looked too deeply into it yet, but it's
what the mount command uses and so I'd assume it supports all the
various options. (Though maybe more than desired due to security
concerns?) Let me know if this has already come up (the big search
machine hasn't found much ;-P).
