This is just a generalized *nix question, really.
I'm not new to *nix, but I've never spent the requisite time to become
knowledgeable about it. Generally, I've just done enough to solve a
problem, then went back to other things.
I *have* however, been at it for a while (TRS-80 Model 16 Xenix running on
was probably my first exposure) - and I've noticed that there's a
longstanding tradition of breaking up a perfectly nice single hard drive
into lots of little partitions for different sections of the file system,
such as root, /usr, /home, and so forth. I've always wondered about this -
it seems kind of wasteful, especially in an OS that allows you to define
your own block and cluster sizes (unlike FAT16, FAT32, etc). I do
understand that SWAP is normally a separate partition, because it's not
(usually) a traditional filesystem.
So - my question - in a single-disk system, why this longstanding tradition
of breaking the filesystem up into multiple partitions? (There! I've
unveiled my ignorance of *nix filesystems in general!)
