Hello !

I am not sure you have to use an initrd file.
You just have to put the kernel with right options on a floppy.
Just change the kernel option with rdev.

I installed Gentoo Linux on a scsi (aic7xx) machine
with Windows 2000. I have two HD, one for each OS.

I don't want to install Grub or Lilo on the HD.
My goal was to boot Linux via a floppy and keep the
Win 2000 boot loader.

I am having a hard time to boot. Need to create
the initrd file.

Do you have a utility to create the initrd in your
distribution?

Do you have a procedure to create it?

Thanks a lot,
Paulo

What about this?

http://www.tldp.org/HOWTO/mini/Linux+NT-Loader.html

- use grub or lilo, but install it on a partition instead of the MBR

a while since I did it, but as far as I remember it worked out fine

For the new SELinux API in 2.6, it is required that the SELinux policy
is loaded by initrd.  We don't have a mkinitrd in portage.  I could add
a Gentoo-fixed RedHat mkinitrd, but I'd prefer not to, since all I have
to do in the initrd is 3 commands (and I don't want to maintain a
mkinitrd ebuild either).  However, there is a static shell in the RedHat
mkinitrd package (nash) that is compiled with dietlibc which I do want,
because its tiny, and made to run in a initrd.

Would it be acceptable to create something like a "mkpolicyinitrd"
package that pulls in the RH src rpm, and compiles nash out of it, and
adds in my own mkinitrd script?  I could also put the mkinitrd in our
selinux-base-policy ebuild, and just create a nash ebuild.

I would rather have a ebuild just for nash.  Is there any preference, or
other suggestions?

I started on some of this before, when I almost needed an initrd for
some boxes (due to crappy hardware, i ended up buying some 3ware raid
controllers instead).

Based on how redhat packages it, I'd suggest a mkinitrd package that
pulls in their srpm (from their RawHide sources as the latest contains a
number of fixed wrt lvm and other things), and builds /sbin/mkinitrd,
/sbin/nash, /sbin/grubby.

As you note that you are not willing to maintain the mkinitrd ebuild, if
you do put it in, I'm willing to maintain it.

Is it not possible to use sash rather than nash ?

No, as sash won't execute scripts.  Nash is more than just a static
shell, it also has useful stuff for initrd's like mount and pivot_root
built in.

Well I've been playing with initrd all day, and I came to the conclusion
that its not worth the effort try to create an in-house mkinitrd (at
least for me to do it).  So I'll put it in as sys-apps/mkinitrd, and add
an optional selinux patch to it.  I pulled it myself from the rawhide
src rpm I got from rpmfind.net.  What is the preferred/correct way of
handling this?  Should I have the ebuild pull the src.rpm and do the
rpm2targz magic in src_unpack, or should I just extract the tarball from
it myself, and put it on distfiles?

That's what led me to buying 3ware controllers myself.

The srpm goes into the SRC_URI, and there is an eclass that does all
the rpm2tgz magic for you iirc.

Dunno if this is helpful, but I make initrds all the time without a
special tool.  This is the applicable snippet from the script that I
use.

  echo Calculating size of root disk
  size=$(( $(du -s ${target} | cut -f1) * 11 / 10 ))
  echo Building root disk of ${size}k
  dd if=/dev/zero of=initrd.img bs=1k count=${size}     || exit 1
  mke2fs -F initrd.img                                  || exit 1
  mkdir -p initrd
  mount initrd.img initrd -o loop                       || exit 1
  cp -a ${target}/* initrd
  umount initrd                                         || exit 1
  gzip -f -9 initrd.img                                 || exit 1

Um, doesn't genkernel build an initrd?  I'm guessing that one could just
steal that code for one's own nefarious purposes.

This is (IMHO) not suitable for Rawhide, as it changes too much.  Do
what I did with elfutils, and rpm2targz it, tar -zxf that, and then
just drop the tarball (only the source) in local-distfiles.
