That's correct. The system mounts a squashfs in the
usbstick/cdrom. The proble is that the modules necessary to mount the
partition in the USB stick (or cdrom) amount to several dozens, since
you have to support all the controllers, plus a few fs types.

I believe that another problem is that the default initrd created by
initramfs-tools include a lot of useless programs (most of them will
be needed only if something goes terribly wrong on boot) so we can
trim more fat on that side.

Thanks for the feedback. I'll keep you posted.
