now we are talking about the same thing, black sabbath albums aside
yes, under raid1, all the partitions would be identical in the area where
the kernels are. however, you still have to update the MBR which is
outside the raid space. this would require copying that block from the
first disk a

what you mention is not possible for the reasons i outlined on non-raid1.
under raid 5- the /boot directory inside the root partition does not exist
on everydisk. it is striped across multiple disks with a parity stripe on
one. lilo would have to pull blocks from different disks, and if one was

The production systems I'm adminin' have very static root
filesystems so, for now, I'm converging on the conclusion
that having two bootable roots and mirrored non-roots is
the cleanest setup.
I'm using 2.0.36 + latest aic7xxx + raidtools 0.42. I assume
I should also apply raid0145-19990128-2.0

Lilo being raid1 capable would be cool, it would be simple enough to have
a 10 meg mirror to have /boot on then / could be mounted from a raid5
or somthing... might even be cool to have the mirror across each disk in
the raid5 then you could guarantee it would find one and boot no matter

Well, I've run a busy file server with 2.0.3x and 0.9x RAID patches from
november/december in uninterrupted production use without a single
problem (at RAID-5). I don't know about the stability of 0.42, bu
ok- the main point with booting is thus- with the new raid code, you can
start raid from the kernel without any utils on the disk. meaning, all you
have to do is get the kernel into ram, and jump to its starting address.
this is what lilo is for, along with loadlin, etc.
they are needed cause the

ot to distant future when time permits and raid 1+ is not so alpha.
If you have specific questions about booting initrd ramdisk, etc... I
will try to answer them or point you to the document with the answers.

Does anyone know of other root-raid howtos? For example,
for those of us who have only a basic understanding of linux
booting and ramdisks?!
I spent the morning looking at the Root-RAID-HOWTO [1]
and have come to the conclusion that doing a root-raid is
seriously non-trivial unless you have a
