Pretty clearly the pros outweigh the cons. ``Giving up a filesystem''? That's a bogus argument. The number of logical devices per physical device is a function of the device driver (which is, of course, subject to hacking). Certainly with the 4.2 FFS you're not worried about making filesystems too large in any ensuing logical device size re-organization? Erik E.

I thought I would write down the pros and cons of mounting /tmp and see what others think. All this assumes at least 2 disks. PRO --- 1) If your users are on the first disk and /tmp is on the second, then both disks are kept busy during compiles, sorts, etc. 2) The amount of writing on the root filesystem is reduced by a great deal. If you crash (we've been crashing a lot but that's another story) the root filesystem will probably still be consistent. This reduces the chance of losing it, along with important files like /etc/passwd. During the past week we crashed about 8 times a day and root was always consistent. CON --- 1) You have to give up a filesystem. I usually use hp1a, which some sites keep an extra copy of root on. PRO 2 means this probably won't be a problem as often but does not protect against a head crash on hp0. 2) You have to set up /etc/fstab and remember to make the mounted filesystem 777 mode too. I've been burned by this, although not for long. -- Just another valley guy Phil Ngai (408) 982-6554 UUCPnet: {ucbvax,decwrl,ihnp4,allegra,intelca}!amd!phil ARPAnet: amd!phil@decwrl.ARPA
