So, your /tmp is larger than RAM size?

If you were successfull building a kernel completely in RAM before, I'd say
quit all unnecessary applications like KDE, firefox, etc. to free up as much
memory as possible...

Notice, though, that if /tmp is getting full and is about the same size as RAM,
the system will start swapping well before /tmp is filled, so you'll get no
performance gain from building in /tmp because effectively you'll be
compiling in the swap partition.

Cheers,
L.
