tmp on tmpfs in the cloud images: good or bad?
The /tmp filesystem is on tmpfs by default in F18:
http://fedoraproject.org/wiki/Features/tmp-on-tmpfs (and affirmed by FESCO
here: https://fedorahosted.org/fesco/ticket/940#comment:45).
I'm agnostic about this as a default for Fedora overall, but I can see it as
problematic on cloud/virt guests where RAM is usually more constrained. (In
fact, there's a bugzilla report to that effect here
https://bugzilla.redhat.com/show_bug.cgi?id=858265).
The feature page and release notes explicitly call out tmpfs as
"Administrators can override this" so I don't think we would be going too
far off the path if we disable it by default in the cloud images.
What do you think?
