Those would have been installed on the /usr partition, not on /var. I think 8 GB might be a quite huge partition, but that will depend on what you intend to use your server for. In some cases /var won't get bigger than 1 GB, on other cases it might fill up quite quickly. % df -h /var Filesystem Size Used Avail Capacity Mounted on /dev/ad4s1e 989M 133M 776M 15% /var This is an example from my home system - you can see that /var is hardly used. > But I had already decided that I was not going to have > separate partitions for /tmp, /var and /usr, but would > want a separate partition for /home, except possibly > on a USB stick. That's a good idea, so you can get rid of partition size calculations. But note that some temporary process might fill /tmp and therefore affect the _whole_ partition that also contains /usr. But maybe that won't be a problem as you put /home somewhere else. > Now it looks like FreeBSD 9.0-to-be is pushing the idea > of installing on GPT; even the memstick installation disk, > where traditional MBR partitioning scheme would fit > comfortably, uses GPT. You can easily apply GTP partitions for the same purpose, e. g. da0p1 for / (including /tmp, /var and /usr subtrees) and da0p2 for /home if you want them on _one_ media - or put da0p1 covering the whole stick to be mounted as /, and da1p1 (second USB media) for /home. > I could build one kernel that would support the hardware > on both computers, or one kernel for each computer. One for each, as you probably will use AMD64 kernel on the "bigger" machine. But you still _can_ use i386 on both of them except you intendedly _require_ AMD64 functionality on the "bigger" machine. > FreeBSD itself can run comfortably in well under 256 MB RAM.

Uhm... printers??? Oh, maybe CUPS, yes. :-) You can _still_ build workstation systems on limited hardware, but you have to be _very_ picky about the applications you use. For example, I have a 300 MHz P2 workstation that runs XFCE 3, Opera 8, mplayer (compiled because of getting the best optimization!), OpenOffice 2, xmms and LaTeX. This system runs well and is still quite usable. > Servers, not needing all the fancy stuff, can be set up on > old computers as long as they're in good condition. I completely agree, as I'm following this philosophy myself. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
