Flo - this is not true. With the appended small patch to debian-cd
2.2.14 (which also corrects a bug in current debian-cd regarding
the handling of the post-boot-scripts, which affects bootable CDs
on alpha, hppa and ppc, please see bug #145318) building bootable
mipsel CDs works like a charm.
I have built a full set of woody CDs for mipsel with it using
"make bin-images", and as an additional test I have built the
first two CDs (the bootable ones) with "make bin-image CD=x".
Booting works fine (tested only on r4k-kn04 as I have no
firmware-supported cdrom drive for my r3k-kn02 box).
I would appreciate very much if the debian-cd folks would accept
my patch.
Regards,
Karsten
