You need the patch from #621803 applying to the maks/run branch? Or was this already applied? This is possibly due to mountkernfs looking for the mount in fstab and mtab and not finding it due to it being mounted as 'none' rather than 'tmpfs' which causes the already-mounted tmpfs to not be found. The patch makes the initramfs use the same mount options as initscripts, and hence not mount a second tmpfs on top of the first. This check is used for all filesystems (re)mounted by mountkernfs/mountdevsubfs. If you already applied the patch, this is not the cause. (By default, initscripts will mount /run if not already mounted by the initramfs. If already mounted, it remounts using the mount options from /etc/fstab, if any.) Alternatively, this could simply be because we haven't yet created mtab at this point. mount_noupdate is used to cause "-n" to be passed to mount to avoid any mtab updates. I'll double check on my systems--I haven't seen this before when testing. If the mtab entry is correct after booting is complete, this is just a harmless warning due to mtab not yet having been created. The "-n" option means no mtab updates, but it may still attempt to read it. As soon as mount switches to a symlink for /etc/mtab, it will never be out of date. I'll take a look later tonight.
