In Wary I now have the suid bit set in /bin/busybox, but apparently that does not mean all the applets can run as root when invoked by a non-root user. In the case of 'reboot', 'poweroff' and 'halt' they won't run.
There is a solution though, a "poor man's sudo", that allows permissions to be set on a per-applet basis. Busybox has to be configured with CONFIG_FEATURE_SUID_CONFIG. I have done this and uploaded the PET. Compiled in Wary, but should work in other puppies (368K):
My script /usr/sbin/root2user now creates /etc/busybox.conf, that allows 'reboot' and 'poweroff' to be run by fido.
The contents of /etc/busybox.conf is explained here:
...can't say that I really understand that 'ssx' field yet!
A distro that uses Busybox is Slitaz, and they also use this mechanism:
I can now shutdown. Other things still broken though (audio for example), will tackle those soon.

would be nice to have that script too.
It is not in the pet so /etc/busybox.conf is empty

Hmmm, I can't get sound to work.
I am using the same technique as kirk in FatDog64, all audio device nodes are dynamically created, with some udev rules. This, as I understand it, should create audio device nodes with root:audio ownership:
Kirk has USER="spot" GROUP="spot".
However, for me the device nodes get created root:root.
Well, I will download latest FatDog64, see if that works for as I expect.

Um, I did download FatDog64, but then realised I don't have a PC with 64-bit CPU.

Not sure whether this is helpful but maybe useful as testing scenario.
seamonkey file:///usr/share/audio/2barks.au using browser as spot.
Or in console
# ps | grep seamonkey
16555 spot 0:00 /bin/sh /usr/bin/seamonkey -UILocale de
16588 spot 0:00 /bin/sh /usr/lib/seamonkey/run-mozilla.sh /usr/lib/seamonk ey/seamonkey-bin -UILocale de
16592 spot 0:20 /usr/lib/seamonkey/seamonkey-bin -UILocale de
19175 root 0:00 grep seamonkey
# su spot
# cat /usr/share/audio/2barks.au > /dev/audio
same good result, heard it loud and clear.
