Hi,
it is a freshly installed RHEL6-x86_64 from iso without updates.
The changes are only in /etc/fstab, as you can see above, and a remount command.

Do you need to execute remount command after host is up?? I need to run every
time
when laptop is up.
Thanks.
Oh sorry,
I didn't realized that you only have the problem after a reboot.
After a reboot I have the same effect.
But the following patch correct it.
The backshlashes marks the linebreak.

If the mount point is different, it works as expected after a reboot
(unpatched rc.sysinit).
cat /etc/fstab |grep tmpfs
tmpfs /dev/shm tmpfs defaults,size=66% 0 0
tmpfs /mnt/tmpfs tmpfs defaults,size=33% 0 0
df -h | grep tmpfs
tmpfs 1,5G 26M 1,5G 2% /dev/shm
tmpfs 984M 0 984M 0% /mnt/tmpfs
It's a bug or a feature?
The command /bin/mount -o remount /dev/shm
in /etc/rc.d/rc.local solve your problem.
Udo
In my opinion it is a bug, because under RHEL5.x works perfectly.
Many thanks Udo.
