Genkernel is just an easy automated way to do that. Or it would be, but the last initramfs it generated for me wouldn't start=20 my=20 md0 (whole-disk software RAID via mdadm) device, which is part of the=20 volume=20 group holding /. [I should try again, perhaps genkernel has gotten smart=20 enough to read my mdadm.conf, ala Debian, and start whole-disk software=20 RAID.] Right now, I get dumped to a shell prompt inside the initramfs each time my= =20 system boots, I then have to start my volume group manually in partial mode= =20 to get (RO) access to the block device / is on. [I don't seem to even have= =20 the right tools inside the initramfs to bring up whole-disk software RAID,= =20 or=20 at least I haven't figured out how.] Then Gentoo tries to boot but fails=20 because it can't mount / as RW (lvm marks lvs in vgs started in partial=20 mode=20 as RO block devices) although it doesn't bail out quickly, so it thinks=20 certain services (like localmount) have started when they haven't. I then log in as root and bring all the lvs to RW status, remount /,=20 restart=20 the 3-4 services that Gentoo thinks are up, and let it continue. In short, my boot process is fsck'd, but I don't reboot enough to have it=20 really bother me. But, this thread isn't really about my troubles even if= =20 some of my setup *is* useful as examples of why you might need an=20 initramfs.
