Nope, no sudo in my live Cd.
Just few pre-made device nodes in fs/skeleton/dev and my special made
init stuff in fs/skeleton/etc/init.d

Well ok, I confess ... I *did* modify /etc/init.d/rcS a little bit for
my needs and also added unionfs mounting to S15mount
and some few other little things

So far I have been very happy with my own personal Live CD Linux distro.
It has 873 MB worth of various userspace utilities in 700 MB CD-R disc.
Feat which would have not been posible without initramfs (XZ
compressed), unionfs and squashfs.

The lowest RAM amount I managed to start it was 192 MB.
With Xorg, Fluxbox and Firefox :-)

Without buildroot and my lil tweakings I could have never made it.

Best regards
Stefan
