You might want to bear in mind that /tmp is on /, not /home. A number
of apps (k3b, for example) sometimes want to write large files (such as
9GB DVD images) there temporarily, and it's puzzling for a user when
Gnome says "13Gb available disk space" but writing a 9Gb file fails.
Partitioning up hard drive space in this manner is not trivial, and the
least surprising option seems to be the standard just-one-partition
If we really want to push the convenience of multiple partitions by
default, I think we'd need something more dynamic. A totally blue-sky
idea would be something like: default to LVM, with /, /home,
swap, /whatever logical volumes and a daemon that watches disk usage and
lvextends a logical volume once it gets over 75% full (or, for added
bonus points, when some process wants to allocate a file that would push
the usage over 75%). Or something.
I don't think the benefits of a separate /home are sufficient to offset
the unexpected failure-cases introduced. Especially since the benefits
are mostly only for power users who will likely set up their own
