I agree!  I just upgraded mine to CyanogenMod too, although it's not
required; I was quite happily running emacs and Ubuntu on an older
JesusFreke firmware before.

The Debian links were added by someone else - I've only tried the
Ubuntu image which I linked to.

Yikes, 4755 certainly sounds mad - however the permissions in my
/system/bin are much saner, so presumably the ubuntu installer doesn't
do that.

That would be great, thanks!

What do you mean by an image file - does yours involve some kind of
loopback?  My Ubuntu install is simply a root filesystem under
/system/sd/ubuntu (and /system/sd is native ext3) therefore a simple
chroot /system/sd/ubuntu plus mounting of /dev/pts, /proc, and /sys
inside it are sufficient to provide the Ubuntu environment.
