HTH although it may be a bit OT. Debian is not particularly sensitive to having many separate mount points, but there are a few limitations to remember: /etc and /lib must be part of /, unless you are willing to roll your own initramfs and can manage to mount them before starting the standard Debian boot process. /var should be a filesystem that fully support POSIX locking semantics, which may mean "not NFS". /home and /usr/local are, intentionally, not (or rarely) written to by the package manager and standard daemons. At the minimum I recommend / and /home to be separate file systems, even for single-user systems. You may also want to put /usr/local on a separate file system, I found it useful to share /usr/local with other distributions before. For a multi-user system, all user-writable locations should be separate file systems from "system" file systems. At the least, /var/tmp, /tmp, and /home should be separate file systems. /dev/shm may be user writable, but in modern system /dev is already a tmpfs file system, so no worries. This is mainly to prevent users of filling up system disks and making trouble for the administrator. In the past, the also prevent a specific type of hardlink attack, but dpkg now prevents that attack independent of file system layout. If you run a daemon that allows users to store data which is put in /var, it should also be separate. I prefer /usr, /opt, and /srv as separate file system as well, but that is simply to keep / small. The most file systems I use is like this: / -- (something fast) /boot -- RAID 1, bootable, of course. /home -- (something large, sharable with other OSes) /opt /srv /tmp -- tmpfs /usr /usr/local -- (something large, sharable with other UNIX/Linux OSes) /var /var/tmp -- (something fast) /var/cache -- (something fast) Debian handles it fine. As far as which file system to use, I have the most experience with reiserfs. The "killer feature" was online growing and offline shrinking. I don't recommend it anymore, but I'm not yet comfortable enough to recommend btrfs for "production" file systems. So, right now I don't have a recommendation. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
