As to the distfiles question, you can safely remove all of them as long as you don't mind downloading them again if, for some reason, something needs to be recompiled. Your real problem is that you've got /tmp (temporary disposable stuff, generally), /var/ (mail, logs, database storage, etc.) and /usr (programs, source, documents, the ports tree, the buildworld target directory, etc), all in your root partition, which is just barely big enough to hold all that stuff unless you do your housekeeping very regularly (and thoroughly). A possible hack, in case you don't wish to backup and reinstall, or learn about growfs(8), [which may be what Nick is getting at by asking for disklabel output]: Move some stuff to your /home partition, and then create symlinks to it from its original location. Some candidates: /tmp, /var/log, /root/, /usr/ports, /usr/src, /usr/obj, /usr/local ... Now, I can't say which would be best; it depends on what's filling up so fast (probably /usr, if you've added X, or really many ports at all) and there might be some security or other issues I'm not aware of, but it's a valid strategy for at least the short term. So, let's say we wanted to move the ports tree and our source tree to /home. As root: # cd /usr # mv ports /home/ # mv src /home/ # ln -s /home/ports ports # ln -s /home/src src Like I said, it's a hack, but it's an available one ;-) Another possibility, though it's possibly more nerve wracking, would be to do something like this: 1. Drop to single user mode in console. 2. Do something like this: change /etc/fstab from: /dev/ad0s4d /home ufs rw 2 2 to: /dev/ad0s4d /usr ufs rw 2 2 Then: #mkdir /home/home #mv /home/* /home/home/ (*note that this will give you one error message, but should still work.) #mv /usr/* /home and then reboot. After rebooting, you will need to make sure that it's possible to get to /usr/home by typing "cd /home", so another symlink would be required. Note that I said, this could be scary --- I don't foresee any potential problems, but if you've never had to recover from a fuzted command using only /bin/sh and the contents of /, it can be a hair-raising experience. Maybe Nick can chime in and say what he thinks; [or someone else --- maybe you should've asked the questions@freebsd.org mailing list, instead of newbies] It might be that growfs isn't that difficult and it is, after all, designed for this purpose.
