Keeping Gentoo Up To Date
These are a few steps I like to run to update my box. If you don’t know what the command does, look it up. I take no responsibility if it hoses your box.
Sync your portage:
emerge --sync
Update all packages:
emerge -DuNqa world
Remove old dependencies:
emerge --depclean -qa
Check for and fix broken libraries:
revdep-rebuild -i -- -qa
Verify you have removed old libraries and fix linking to them:
RM="";
REVDEP="";
for i in `zgrep "# rm '" /var/log/portage/elog/* | cut -f 2 -d "#" | sort -u | sed 's/rm //'`;
do
RM="$RM $i";
REVDEP="$REVDEP|$i";
done;
if [[ -n $RM ]];
then
echo &&
echo `echo $REVDEP | sed s/^\|//` &&
echo &&
revdep-rebuild -i `echo $REVDEP | sed s/^\|//` -- -qa &&
echo &&
echo `echo $RM | sed s/\'//g` &&
echo &&
rm -i `echo $RM | sed s/\'//g`;
fi
Update your configuration files:
etc-update
Show which process need to be restarted:
lsof -n +c0 | grep 'DEL.*lib' | cut -f 1 -d ' ' | sort -u
