Moving to snapd as the error is:
- Run install hook of "lxd" snap if present (run hook "install": cannot perform operation: mount --rbind /var/tmp /tmp/snap.rootfs_1DwCoc//var/tmp: Permission denied)

This isn't logic from the LXD snap itself but something that snapd is performing.

Is /var/tmp a symbolic link? I think we only handle a case when that is a real directory.
