System Administration Practice

Kept updated portage tree

Even if you're not doing a full update every day, you should sync the portage tree and overlays regularly. It will reduce the time that you need to sync tree before a system upgrade. Also, if you just want to install something, it will be installed with latest deps so you will not waste time on upgrading it later. Here is an 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 {} \;
