I strongly recommend that you install the package "kernel-package" and use 
make-kpkg to build the kernel.  This builds nice Debian packages of the 
kernel which make it a lot easier to manage and track which machines are 
running which versions.  Also the kernel package installation takes care of 
making the initrd.

Hmm.  That doesn't look like the right command to get a fully functional 
initrd, also it puts all the kernel's modules into the initrd which isn't 
necessary (and if your kernel settings are like mine you'll get a 2M initrd 

I've written some scripts to help manage this.  I've attached two scripts for 
inclusion in /etc/mkinitrd/scripts directory (make sure you don't run the 
devfs script in any other way), and the mkinitrd.conf file I use.  With that 
and the correct /etc/mkinitrd/modules file it should all work fine.

Well if your kernel is on /dev/hda3 then it is 03:03 so that part is OK.

Firstly if you suspect a problem in a package then probably the best option 
is to contact the package maintainer (in the case of devfsd it's me).

Devfsd is necessary on all systems running devfs, and most systems won't 
complete the boot process without devfsd running.  However it won't affect 
the ability to mount root.

When you say "re-make the kernel without DEVFS support and ext2 in the 
kernel" are you saying that you make it with "ext2 in the kernel" or "without 
DEVFS support and ext2"?

I think that what you are doing with ext2 is what makes the difference...

I've CC'd this message to the debian-user list which is more appropriate for 
this discussion.  I've BCC'd debian-devel so people can see that it's moved 
to the user list.

Please CC me on all further discussion.
