There must be good reasons for > this. There are a number of reasons, not all of which will apply to any given situation. 1) [as Wojciech Puchar said] tradition. Not an especially good reason on its own. 2) keeping problems on one partition from raising trouble on another partition. e.g., filesystem corruption in a home directory keeping the root from being able to boot, or filling up a mail directory keeping people from logging in. 3) fsck: Background fsck can't be done on the root filesystem, so if you have a large root, that amounts to a substantial delay booting after a crash. 4) backups: dump(8) works on a filesystem basis, so organizing the data for backup (with dump) means organizing according to filesystem. The same applies to snapshots. -- Lowell Gilbert, embedded/networking software engineer, Boston area http://be-well.ilk.org/~lowell/
