I use the following on my laptop: Filesystem Size Used Avail Capacity Mounted on /dev/ad0s2a 248M 97M 131M 42% / /dev/ad0s2e 248M 17M 211M 7% /tmp /dev/ad0s2f 48G 11G 32G 26% /usr /dev/ad0s2d 248M 95M 133M 42% /var (some, such as devfs, trimmed from output) If you are looking to build a production machine, it is recommended, if you can calculate it, to create seperate partitions for /var and /tmp. That way if a program runs away and starts filling your system, with logs or other garbage, it will fill the partition and not impact other critical areas of your system. On my server, I have a similar layout, however I'm using 1Gb each for /var and /tmp. You should give /usr a lot more than 8Mb, because as your system grows, so will /usr/local. All of my custom built software goes in /usr/local, and as such you will need to give it a lot of room to move. The FreeBSD ports collection also resides on /usr, and the more software you compile, the more disk space it will need to extract and compile. My /usr/ports tree is currently 1.1Gb. I don't clean it up very often, so there are plenty of 'work' directories strewn throughout it. /usr/src is also stored on the /usr partition, should you choose to install it. Mine is currently 368Mb. You'll need disk space free on /usr if you ever wish to recompile your kernel, as the compiling is all done in /usr/obj. The /home directory, by default, is also stored on /usr/home. It is just symlinked as part of a base install to /home. Of course, you can make this partition, like any other, completely seperate and give it any size you like, but depending on the role of your system, you may just wish to set your partition sizes for /, /tmp, /var, and then give the rest to /usr. Unless you have a specific requirement for giving your home directories a smaller amount of room, then you should do this. If you don't have a seperate disk for data, most of your data will get stored in your home directory. Where possible, I have always set up FreeBSD machines with two disks: one for the base system, including /usr, and the other I mount as /data. This disk is a physically seperate disk and I use it for data storage. That way I can take it out of one machine and put it into another without having to worry that I'll be taking my core installation with it.
