Hi, Gentoo. My new(ish) amd64 system has two 1TB HDDs in a (software) RAID1, and practically the entire system is under an LVM2. I rather unwisely made this addition to the startup stuff: ls -s /usr/bin/svscanboot /etc/init.d/ rc-update add svscanboot default , and now the box hangs

Hi, I'm going to re-install gentoo on a small hobby-server and because I need both redundancy and flexibility, I thought in addition to raid1 (2x 160GB ata-disk) this time I would also use lvm2: /dev/md0 /boot (~50MB) /dev/md1 / (2GB) /dev/md2 swap (2GB) /dev/md3 lvm2(rest for /var
