Why doesn't SLES 10.3 has /dev/shm?

Question

It's strange that on all of our Linux systems there is a separated filesystem: /dev/shm. But there isn't any on SLES 10.3 machines, because it's just a directory on them.

My question: Can someone provide an offical source what states that SLES 10.3 doesn't use a separated /dev/shm?

SLES 10 SP4:

$ mount | grep tmpfs
udev on /dev type tmpfs (rw)

Not sure about SP3, but I would expect it to be similar.What other systems are you comparing SLES 10 SP3 to? It's rather old and things have changed over the years...

OK. Why are you actually missing it? /dev/shm is in tmpfs anyway in this setup. – peterph Feb 03 '14 at 20:36
Looks like all other distros have it as separated FS & it would be useful if we would have it separated on SLES 10 too, but we don't know why isn't it by default there.. – gasko peter Feb 05 '14 at 14:19
From the practical point of view - why just not modify /etc/fstab accordingly? – peterph Feb 05 '14 at 17:04
