I thought I had shorn up that edge pretty well by doing a test upgrade
on a copy of the machine, but I guess I missed something.

via the 5.0 RC2 build off ftp.netbsd.org. I actually have all the
sets extracted into a directory, but since I need to set LD_LIBRARY_PATH
to run things out of there I can't run setuid programs like su. (it
needs libpam, which isn't in /lib)

Yeah, it's the same problem, even with sh (or any other binary):
sudo -u root /bin/sh
sudo: unable to execute /bin/sh: Resource temporarily unavailable

heh, my plan is to run xen on the machine. Upgrading to netbsd 5
is supposed to be the first step in that.
