Wow, this did impress me (backwards ;-) ! server with single partition / (plus swap partition) ! It was - I forgot how long ago - when I start feeling myself as admin building more robust systems when I started meticulously creating different partitions for all things that shouldn't affect each other. And still I will keep doing that because of following. Do you want some unprivileged user's script writing into /tmp to fill up (or run filesystem out of file handlers) / partition holding other things like mail spool, or database storage? BTW: on mail servers where my users can log in I always mount their home directories, and spool with "noexec, nosuid, nodev" options (the same goes about /tmp, and wherever web server stores uploaded stuff...). I do have a feeling that the trend is opposite the one you mentioned: people are switching not to linux, but away from it. As linux lately (say, last 3 years or so) became more like windows: once every 45 days on average: kernel update ==> reboot. I remember way back (2.4 kernels) we had a bunch of linux machines with uptime 2 - 3 years... Not any more. Sorry, I just couldn't hold myself ;-( Valeri On Fri, February 10, 2012 10:16 am, Roger Marquis wrote: >> I am having an issue with one of my jailed systems. It has run out of >> space.
