sparc32: ESP not included in initrd

[ludo@chbouib.org (Ludovic Courtès)]

Hi,

While upgrading from a 2.4 kernel to `linux-image-2.6.18-4-sparc32' on a
SPARCclassic, I noticed that the `esp' module is not included in the
initrd that gets generated (consequently, the new kernel hangs "waiting
for the root filesystem" upon reboot).

This is easily fixed by, e.g., adding `esp' on a single line in
`/etc/initramfs-tools/modules' (if `mkinitramfs' is being used).
However, it'd be obviously nicer if this was done automatically when
installing the package.

I vaguely recall discussions about such problems on this list but I
don't remember whether it was supposed to be fixed already.

Thanks,
Ludovic.
