My current set up uses a /swap partition which is 2x my memory size
mem = 256 MB $ sudo /sbin/fdisk -l /dev/hda6 76506 77545 524128+ 82 Linux swap
For low memory systems, this logic is okay, but as your memory grows, you don't need to keep doubling the size for swap. For example, on a system with 2Gigs of ram, there's no reason to have 4G of swap space.
I'm interested in the use of a file for swap, as I hear that there is now no speed penalty for that. I use ext3 for my partitions.
Using swap by itself is generally a speed penalty. Using a file for it can be done, but it's not really something I'd do.
I'm also interested in whether it be reasonable/desirable to make /home, /tmp, and /var be on a separate partition. I have heard arguments on both sides, some claiming that with ext3 the system won't become unbootable because of /tmp filling up.
This depends entirely on the tasks required of the box. Putting /tmp on a separate partition can allow you to mount it noexec, which can help with security, and filling up /tmp won't fill the rest of the disk. /home on a separate partition can be a good thing for major upgrades or re-installs, as you can do a completely clean install and format the system without nuking user data. /var is the most task dependent because this is where the webroot and database files live by default. Splitting /var and subdirs out based on task can be beneficial. -- During times of universal deceit, telling the truth becomes a revolutionary act.
