Since yesterday, my boot log show a message :
mount: none already mounted or /dev/pts busy
mount: according to mtab, /dev/pts is already mounted on /dev/pts
This is my /etc/mtab content :
proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0
sys /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0
udev /dev devtmpfs rw,nosuid,relatime,size=10240k,nr_inodes=497620,mode=755 0 0

gvfs-fuse-daemon /home/chris/.gvfs fuse.gvfs-fuse-daemon rw,nosuid,nodev,user=chris 0 0
Everything keeps on working though. But also my shutdown sometimes hangs when it comes to unmounting the local filesystems.

Is it something that always worked for you but stopped after an update?

Same here; both on desktop and eeepc.

It might be initscripts / udev -related. Try to downgrade and see if the issue goes away.

I don't have a problem with it mounting or umounting... but since the last update of initscripts... I did notice a line in the logs whereas it 'fails to umount tmpfs'.
SOLVED *** UPDATE: 5-17-2010 ***
I followed the posted below.. so prior to fixing the /etc/fstab I umounted /dev/shm -- then I edited /etc/fstab by adding a preceding '#' to /dev/shm in my fstab. After a reboot or two, it was solved. So the 'fails to unmount' doesn't happen anymore. Thank you.
Old /etc/fstab:
shm /dev/shm tmpfs noexec,nodev,nosuid 0 0
Changed /etc/fstab:
#shm /dev/shm tmpfs noexec,nodev,nosuid 0 0

Remove /dev/pts and /dev/shm from fstab or...
If you have custom options for these filesystems: put as "source" (change "none" to "devpts", and "none" -> "shm"). (New util-linux[#1] puts null string when "none" is used as source).
Do the same with all other entries with "none" as source, put any name

Downgrading the initscripts package solved the problem for me.

It's not a bug, as explained by djgera.

Thank you djgera, karol, Kilzool, Strider, brain0.
My /etc/fstab files indeed contained:
none/dev/pts devpts defaults 0 0
none /dev/shm tmpfs nodev,nosuid 0 0
And there indeed was a fstab.pacnew from Oct 2010 stating that it should be:
devpts /dev/pts devpts defaults 0 0
shm /dev/shm tmpfs nodev,nosuid 0 0
Changing file system names from none to devpts and shm, solved the problem for me.

All,
after another busy working day I noticed a lot of replies to my post and my bug got closed as not being not a bug, interesting .
@ djgera : I did read your post but I assumed it did not apply to me since I have neither /dev/pts/ nor /def/shm in my /etc/fstab ! Those only appear in /etc/mtab.
Anyway, I thought I might have overlooked something so I applied djgera's changes to my mtab file (as opposed to the fstab file) which according to me was not very logic but one never knows. I upgraded my initscripts and performed a shutdown ... which hung. I did two types of changes to mtab : one that changed 'none' to xxx and one that deleted the lines altogether from mtab. But all was to no avail : two times my shutdown hung and my boot showed the same error messages.
I downgraded initscripts again and all was (again) back to normal.
I think I have to look further the udev route as mentioned by karol.
Any advice is still more than welcome, all your comments made so far are highly appreciated.

I have finally solved the problem :
1) for boot up : I apparently did not look correctly in my /etc/fstab : /dev/pts and /dev/shm are indeed in there. I applied the patch by djgera and I do not have any error messages anymore
2) but my shutdown still hung after the message 'unmounting local filesystems'. The hung was caused by ... plymouth I removed it from my kernel image and gone was the hung. So bye bye plymouth
Thanks for the help once more
