Basically we used to &quot;fake&quot; the mount state with a file in /etc/mtab.
This is now a symlink to /proc/mounts which, IMO is much safer. This is
why the &quot;mount&quot; output has gotten bigger.

As for rootfs staying mounted, I believe this is in some way due to the
ability to re-enter the initrd on shutdown/reboot. This allows for nice
things such as unmounting / and shutting down lvm properly before
poweroff/reboot which was not possible before. So IMO this is an
improvement, albeit I agree it's a bit ugly.

If it's not that, then it's maybe to do with the /dev mount which must
be preserved between initrd and proper / in order to transfer important
udev metadata.
