If I ran a machine with users on it, I might agree :-) But there's just me and I set TMP and TMPDIR to /var/tmp which many programs used to pick up on when I first set them years ago. sort does, for e.g. and that was always a tmp killer in the kind of environments I worked in. Plus *I* know to use /var/tmp. Nowadays my /tmp has a small number of sockets and gubbins so I doubt softupdates would make any perceivable difference to me.

Do the install again but do not make /boot a partition. 1Gb is more than ample for / and /boot. Given that you have /tmp separately, 256Mb would do. I, at least, never used that much even. /dev/ad12s1a981527 122405 78060014%/ 1Gb just because it's peanuts to a 200Gb disk, and I don't bother with /tmp separately. For all the talk of the 1024 cylinder problem, I have never encountered it. I suspect that while it was true of older hardware, that it just isn't the case any more. If this is a problem, then it is just the / (root) partition that needs to start inside 1024 cylinders. Apart from that, my opinion is that having swap = 2.5 * memory is still a reasonable rule of thumb. You may never need it but a) it's a tiny fraction of your disk and b) if you expand your memory in the future you still have enough swap. You must have at least as much swap as physical memory. With 1Gb I put in 4Gb of swap, just because it's peanuts compared to a 200Gb disk. If I double my memory, I still have plenty of swap. /var depends on what this machine does. If it is a mailserver then 512M is inadequate, for a home machine it's probably plenty. If you ever need a crash dump from the kernel (and you may *never* need one, but if you do...) then you need as much free disk space as you have physical memory. There was a recent thread about disk sizing (maybe a month ago?) so try searching the archive. I also found this useful when clarifying my thoughts about how to partition a new disk: http://keramida.serverhive.com/weblog/archives/2004-10-26/daemonizing-a-new-disk --Alex ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: Did we must put the mounted partition '/' and '/boot' in the same slice ?
I put '/boot' for an individual partition just for 1023 cylinder story, although FreeBSD did not need this action ! the following is my partitions layout, pls help to do some check: ad0s1d /boot -> 30M ad0s1a / -> 512M ad0s1b swap -> 512M ad0s1e /usr -> 6144M ad0s1f /var -> 512M ad0s1g /home -> 2017M ad0s1h /tmp -> 512M But after I finished my installation and reboot FreeBSD, it will not load sccuessfully!
