System Administration Practice

Kept updated portage tree

Even if you do not doing full update everyday, you should upgrading portage tree. It will reduce time what you may need to sync tree before system upgrade. Also, if you just want install something, it will be installed with latest deps so you will not waste time on upgrading it while full system upgrade. Example script to upgrade portage and overlay every day

Code: /etc/cron.daily/autosync.sh

#!/bin/bash log="/var/log/autosync.log" if [ ! -f $log ]; then touch $log chmod 600 $log chown root:root $log fi echo >> $log echo "*** autosync started! ($(date +'%d-%m-%Y %H:%M:%S'))" >> $log echo "*** running emerge --sync" >> $log emerge -q --sync >> $log 2>&1 if [ -f /usr/bin/layman ]; then echo >> $log echo "*** running layman -S" >> $log /usr/bin/layman -S --nocolor >> $log 2>&1 fi

Purge unused distfiles

Distfiles may took a lot of space, if you do not clean them from time to time it may be an issue. There is many way to cleanup them.

• Remove distfiles which wasn't accessed in last 90 days. (WARNING: It will not work if distfiles are on filesystem with noatime option. You may want think about relatime).

Code: /etc/cron.daily/distfiles-auto-purge.sh

#!/bin/bash find /usr/portage/distfiles -maxdepth 1 -type f -atime +90 -exec rm {} \;
