As others have pointed out, you probably have /var on your root file system. You obviously didn't follow the book to the letter. I recommend a 32 MB root file system, which probably needs upgrading to 40 MB, but never to 100 MB. I do, however, recommend not to have a separate /var file system, and on page 87 I explain what you need to do. It's probably best to reboot after doing these steps. I'm appending a plain text version. Greg Where to put /var and /tmp __________________________ Now the installation is completed, but you may still have some housekeeping to do. Did you include a /var file system on your disk? In the example, we didn't. If we don't specify anything else, /var will end up on the root file system, which isn't enormous. If we leave things like that, there's a very good chance that the root file system will fill up. We solve this problem by creating a directory /usr/var and a symbolic link /var which points to /usr/var: # mkdir /usr/var create a new directory # cd /var move to the old /var directory # tar cf - . | (cd /usr/var; tar xf - ) copy its contents # cd / get out of the directory # rm -rf /var and remove it # ln -s /usr/var /var now link to the new directory After performing these steps, you might see messages like: Jan 9 13:15:00 myname syslogd: /var/run/utmp: no such file or directory syslogd is the System Log daemon. [1] Don't worry about these messages. If you're intending to restart the system soon, just wait until then and the messages will go away. Otherwise you can restart syslogd: # ps waux | grep syslogd look for the syslog daemon root 152 11.0 1.6 176 476 v0 D+ 1:16M 0:00.15 grep syslogd root 58 0.0 1.1 184 332 ?? Ds 1:13 0:00:57 syslogd # kill -9 58 stop the PID of syslogd # syslogd and start it again The PID of the syslogd is the second field on the line which ends with just syslogd. The first line is the process which is looking for the text syslogd. See Chapter 11, Making friends with FreeBSD, page 224, for more information on stopping processes. Programs should not write large files to /tmp; if a program needs to create a large temporary file, it should create it in /var/tmp. Unfortunately, the location of the temporary files is not usually in your hands. It would be tempting to also replace /tmp with a symbolic link to /var/tmp, but the system handles /tmp and /var/tmp slightly differently: after a reboot, it removes all files from /tmp, but it leaves the files in /var/tmp. You can solve this problem by creating a directory /usr/tmp and creating a link to it. Perform the following steps in single-user mode (see Chapter 11, Making friends with FreeBSD, page 244, for a description of single user mode and how to get into it). # mkdir /usr/tmp create a new directory # rm -rf /tmp and remove the old /tmp # ln -s /usr/tmp /tmp now link to the new directory -- When replying to this message, please copy the original recipients.
