I'm sorry, this is easy to fix... have a set of tools you copy to /ibin that are used for the install (all staticly compiled binaries hopefully) and run the install world out of /ibin... maybe include some binaries for system recovery to make sure... if people are interested, I can take a look at it... it'd be interesting to be able to do something like; make prep-installworld; rm -rf /usr/{sbin,bin,lib} /{bin,sbin}; make installworld and have it complete... :) -- John-Mark Gurney Voice: +1 408 975 9651 Cu Networking "The soul contains in itself the event that shall presently befall it.
