7.5. Slackware

Slackware 8.1 requires no updating of boot time scripts in order to make LVM work.

For versions previous to Slackware 8.1, you should apply the following patch to /etc/rc.d/rc.S

cd /etc/rc.d
cp -a rc.S rc.S.old
patch -p0 < rc.S.diff
            
(the cp part to make a backup in case).
