Everything I have ever read about disk management tells me that smaller
file systems on a disk are more efficient than large ones. There are far
fewer inodes to check, for one thing.
I'm not sure if you really mean partitions or file systems. I would
strongly recommend your boot disk be split into at least 2 file systems.
One for /dev/root, and only put the O/S and things that can't live
anywhere else there. The rest of the disk could be a 2nd and/or 3rd file
system. Have the O/S on its own file system allows you to reload your
O/S without having to reinstall all your software, or cherry pick
applications out of a tape archive taken prior to the reload.
You do need to be concerned about fragmentation with Unix, but I believe
there are fsck options that can reorganize a file system somewhat. I'm
not totally familiar with though, so I won't hazzard a wrong suggestion.
You get a tremendous feeling of wealth with lots of disk space...but it
always seems to get used up again somehow.....
