I still create separate partitions through paranoia, to avoid corrupting the entire disk if for example /usr/obj is being written to when the power goes out. I don't know if that would happen but I've had too many problem over the years with various filesystems that I don't trust it. With ZFS I've gone even further and created separate filesystems for /usr/src, /usr/ports etc. The output of 'mount' looks somewhat like a Solaris machine now :) I have a task on my TODO list to increase the sizes of the partitions in sysinstall: for example / goes to 1GB, /var to 4GB.

Re: /boot is full after running make installkernel on FreeBSD 8.0
A healthy fear, indeed. For one thing, I'd certainly rather have someone do rm /boot/kernel.old/*.ko than rm -r /boot/kernel.old. Being even more selective is an obvious extension... Why not move the old useless kernel to another drive. Sure if the system kernel fails and you need the old one, there is a little bit more work, but nothing that I can't see be solved by: 1. booting from a livecd 2. mount the /boot and /theotherpartition 3. move the kernel back and move the faulty one away 4. reboot That saves you from deleting the entire computer/world/Internet and save the old kernel as well. However, I have never done this myself but the theory sounds good. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: /boot is full after running make installkernel on FreeBSD 8.0
Since it would be smart to have at least one known, good kernel, why not make the / partition maybe 1G? I know the smaller the / partition, the better the performance (since it's the first partition of the drive), but I can't imagine a slightly larger / partition would impact performance that much, do you think?

Multiple partitions still isn't a bad idea if you ever have to fsck and even on a desktop / laptop I usually mount /tmp as noexec. (note: installworld requires exec in /tmp, so you will have to remount /tmp if you use that). Also, it's easier to recover if you can boot single user mode and run a quick fsck on / when it's small. It doesn't happen often, but when it does it's easier. One thing I didn't see is a /home. Is your /home under /usr or /? I have a 8-STABLE system with both kernel and kernel.old and they only take up 520MB or so. I normally make my / 2-4GB and then mount a separate /var (2-10GB depending), /tmp (2-10GB depending) and /usr (15-50gb depending) and /home (the rest) . A separate /home is very nice if you're rebuilding or re-installing you can just not format that partition and all your stuff will still be there. Of course, have backups as well :) Henrik -- Henrik Hudson li...@rhavenn.net - God, root, what is difference?

Re: /boot is full after running make installkernel on FreeBSD 8.0
Henrik, When I FIRST installed 8.0, I did create a separate /home partition. When I installed the kernel and starting running out of space in / , I thought O.K...I'll let FreeBSD make the partition sizes IT wants to and see if I have the same problem, and I did. Apparently, 512M is just, not, quite big enough so I think I'll try 1G to give me plenty of room.
