% cat /proc/mounts | grep ' / '
rootfs / rootfs rw 0 0
/dev/disk/by-uuid/... / btrfs rw,relatime,ssd,space_cache 0 0

The root filesystem is only mounted once; this is the second line.

The first line "rootfs" is actually the initramfs from when the
system booted.  The real root filesystem is mounted inside this
on /root, but it's not visible on the running system.

The only change here was that when /etc/mtab was a static file,
we didn't add the initramfs to it.  But now that we use /proc/mounts,
the information which was previously hidden is now visible.

Roger
