Your guess is correct :)
The reason I avoided select() was that there is more than one target in
the mbx/boot directory (I think they are zImage, zImage.initrd, znet,
znet.initrd). I was not sure how to use select with these options as
they all use the same source files. It seemed very repetitive to have
multiple base_target() and select() statements. I have no problem with
multiple base_target() statements but repeating the select() statements
for each base_target() statement seemed to verbose and prone to
copy/paste errors ;-)
There is probably a better way. Any suggestions ??
Thanks,
Brendan Simon.
