DMRaid mkinitrd

[Mark Wormgoor]

Hi,

Nope.  My hacked Anaconda didn't add an alias scsi_hostadapter sata_sil to
/etc/modprobe.conf, so my initrd did not include the libata or sata_sil
modules.  That suddenly came to me this morning ;-)

Anyway, I'm typing this from a running Fedora-devel system just booted
using dmraid.  I only had to do some small hacks to mkinitrd and
rc.sysinit to get it to boot.  Unfortunately, my rootdev is now hardcoded
into mkinitrd.  I'm going to try and figure out if I can improve on that.

Also, I need to look at my Anaconda hack to see if I can get it to
properly update modprobe.conf.

Then, I will try Erik's patches to lilo and see if I can ditch my FC1
installation after FC3 final comes out (I still need FC1 to run lilo after
every update to initrd; wouldn't grub be nice now).

Kind regards,

Mark
