The disklabel editor in Sysinstall has an 'a'uto option that will give you some conservative numbers that may work for small/medium workstations. Power users like me need more :) /: Your root FS. Contains the kernel and basic system binaries and /tmp. I run mine at 50mb, which seems to work fine for everyday work. /var: Contains logs, mail spool, printer spool, etc. Should be big enough to hold this w/o filling. I run mine at 50mb. SWAP: Depends on usage. Equal size with memory is a good start, or if you don't have much RAM, then scale to 2x or 3x. If you plan on running XWindows then double that. With 32mb of RAM, I have a 100mb swap partition and use a small chunk of it. On the old disk, I had 16mb of RAM and 32mb of swap running X. I could fill it if I started up some really big mbone tools. I was swapping if I started an xterm, and that slowed things down quite a bit. The current config fits everything in RAM with a little spillover, depending on what I"m doing at the moment. > what types of programs use the SWAP a lot? Xwindows and associated programs will gobble up ram pretty quickly and force you to swap. Netscape and Xemacs are really bad. Here is my df and swapinfo for reference. gdi,ttyp4,/dev,18>df -k Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/wd0a 49231 34225 11068 76% / /dev/wd0e 49231 13775 31518 30% /var /dev/wd0f 824143 583304 174908 77% /usr procfs 4 4 0 100% /proc gdi,ttyp4,/dev,19>swapinfo Device 1K-blocks Used Avail Capacity Type /dev/wd0b 102400 2760 99576 3% Interleaved Hope this helps.
