[gentoo-dev] 2.2 kernels under gentoo

[gentoo-dev] 2.2 kernels under gentoo

[David Nellans]

i made an attempt to use a 2.2 kernel gentoo system as described in the
install faq, and also attempted to drop a 2.2 kernel into a machine thats
been running gentoo for almost a year now.

in both cases the kernel will boot but when INIT loads it returns
Fatal: kernel to old and hangs hard.  I can't find any references to
kernel versioning being a problem in the util-linux changelogs so i'm
wondering if this is actually more of a problem with the gentoo
init-scripts that is only appearing as a problem with INIT?

has anyone heard of anyone actually using a 2.2 kernel sucessfully in a
gentoo system, if so please let me know as i'd like to get the docs for
doing it correctly updated!

I believe the gentoo glibc build process set's the minimum kernel version to 
2.4.0. As 2.2 is really incompatible for this glibc it doesn't work. 
Recompile glibc to allow for 2.2 kernels and try again.

I know it used to work, but I haven't tried it in a good long time.
What flags did you pass to the kernel?

Please do post a bug on bugs.gentoo.org if you haven't done so already.

kernel /boot/CMKernel root=/dev/hda1 rootfstype=ext2 vga=791
gentoo=notmpfs,nodevfs

is what the grub line looked like in both cases for the drop in or the
new system.  ram disk support is compiled into the kernel in both cases.

i googled a bit for similar errors and found some people who claimed
that this error and others similar could come from building things like
libc under a 2.4 kernel and then trying to use it under a 2.2 kernel. 
i'm a little skeptical of this though... any thoughts?

i haven't posted a bug yet because i'd like to make sure its not an
error on my part!

I've never used the rootfstype flag, but otherwise everything looks
right.

Oh, dear.  Um, it might well be possible.  It is true that glibc builds
against an installed set of linux headers (that's why we have a
linux-headers package in Portage), so if you have a spare partition
available you might want to try bootstrapping again in a chroot on that
partition, only edit /etc/make.profile/packages to limit the
linux-headers package to be less than 2.4 beforehand.  Then try to boot
into that partition.  (You may need to build a 2.2 kernel in the chroot,
but I'm really not sure.)

Please go ahead and post a bug anyway.  Otherwise things tend to get
lost.  Also, more developers read the bug reports than actually read the
mailing lists (since the gentoo-dev traffic can get pretty high).
