root mounted twice since devfs upgrade

I've just upgraded to 2.4.19 kernel and decided to switch to devfs.
While booting I had an error saying that proc couldn't be mounted cause
it was already. I just removed the rcsysinit.d/S20mountproc and it
But I've noticed that if I do df -ah rootfs shows twice:
#:> df -ah
Filesystem Size Used Avail Use% Mounted on
rootfs 1.4G 70M 1.3G 5% /
/dev/root 1.4G 70M 1.3G 5% /
none 0 0 0 - /dev
none 0 0 0 - /proc
/dev/sda6 630M 35M 594M 6% /var
/dev/sda3 3.7G 619M 3.1G 17% /usr
/dev/sda5 2.3G 1.3G 1.0G 55% /home
a cat /proc/mounts give me this:
#:> cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / reiserfs ro 0 0
none /dev devfs rw 0 0
none /proc proc rw 0 0
/dev/sda6 /var reiserfs rw 0 0
/dev/sda3 /usr reiserfs rw 0 0
/dev/sda5 /home reiserfs rw 0 0
I think it comes from devfs but I don't know how to solve this.
Using dmesg I've noticed that my root partition is checked before devfs
reiserfs: checking transaction log (device 08:01) ...
Using r5 hash to sort names
ReiserFS version 3.6.25
VFS: Mounted root (reiserfs filesystem).
Mounted devfs on /dev
Freeing unused kernel memory: 220k freed
Adding Swap: 499704k swap-space (priority 1)
So I think that my root partition is mounted once by devfs and another
time by something I can't identify.
Somebody may help me?
btw: I'm using lfs-3.3 with a 2.4.18 patched to 2.4.19 kernel and
# filesystem mount-point fs-type options dump fsck-order
#/dev/sda1 / reiserfs defaults 0 0
/dev/sda2 swap swap pri=1 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto defaults,user,noauto 0 0
/dev/sda6 /var reiserfs defaults 0 0
/dev/hdc /cdrom iso9660 defaults,ro,noauto,user 0 0
/dev/sda3 /usr reiserfs defaults 0 0
/dev/sda5 /home reiserfs defaults 0 0
There are lot of links related to devfs mounted twice or rootfs mounted
twice because of ramdisk or such things, but I didn't find the
corresponding on google. There was a thread about this in 2002-04
archive but it didn't help me as the guy switched back to 2.4.18
without saying if he kept devfs so I'm a bit confused.
