Well, Debian switched to initramfs since 2.6.12 or so. Initramfs is
a joint development by the Ubuntu and Debian folks and it's just
a gzipped cpio file; that's a lot easier to deal with than cramfs.

/etc/initramfs-tools/modules will be an /etc/modules-style file that
determines what the initramfs loads.
/usr/share/initramfs-tools/hooks/* contains hooks
which installs any non-standard modules into te initramfs. The
scripts in /usr/share/initramfs-tools/scripts/*/* load them during

I think it'll be on a case-by-case basis. To start, maybe you could
let me know which raid modules are loaded. I am the Debian RAID
maintainer and unless you use RAID, no modules should get loaded.
If you could list the modules you don't need, and also let me know
which hooks are being run, that would help,

My book is based on Debian sarge. A lot has changed for Debian etch.
I am sorry. :)
(I am working on a new edition, but it's going to take substantially
longer than etch itself).

it is better to remain silent and be thought a fool
