Hmmm. /tmp is definitely one thing I would take out of / and put in its own partition - or at least in some other big scratch space. It can easily get filled with stuff which then goes away. But if it overfills /, it can bring the system to its knees. If it overfills its own system, it can make things slow to a standstill, but usually you can still get in with root and nuke enough to continue and at least shut things down gracefully. ////jerry > > Kevin Kinsey > -- > Life is what happens to you while you're busy making other plans. > -- John Lennon, Beautiful Boy
