Heya!
Please be aware that since the most recent systemd uploads /tmp is now
in tmpfs by default in Rawhide/F18.
For details please see this feature page:
https://fedoraproject.org/wiki/Features/tmp-on-tmpfs
If you have an explicit /tmp entry in fstab things should continue to
work the same as before. If you don't then you will now get a tmpfs on
/tmp by default.
This will most likely lead to a problem or two with software that isn't
happy about /tmp being small. We have created a tracker bug to keep
track of this:
https://bugzilla.redhat.com/show_bug.cgi?id=826015
If you have identified a bug that is triggered by /tmp being on tmpfs
now, please add it to this tracker bug!
For a bit of background on all of this and recommendations for
developers, please see:

Lennart is there any smarts about it based on available RAM ?
I regularly install VMs with < 1GiB of RAM and /tmp in RAM would make
them unusable.
On a development laptop with 4GiB of RAM and many VMs I would still
find /tmp in RAM a bit of a stretch, but whatever.
So is there any smarts there that disable this feature when there is
little RAM available from the get go ?
Simo.
