I have a version of rpm-2.5.pre6 which does not require any configuration
files to be present. Default rpmrc and rpmpopt are compiled into the binary.
There still is a problem upgrading rpm binary itself, however it can be
partially avoided by copying rpm binary to /tmp and running it from there.

Source rpm is available in ftp://ftp.ultra.net/pub/eugene/SRPMS directory. I
can provide a binary upon request.

For general rule of upgrading locked files the best information I found so
far is from the book "Bulletproof installs" by Leslie E. Easter. ISBN
0137980914. The idea is to schedule a rename operation upon next reboot. It
is done via registry on NT and wininit.ini file on W95.

Eugene.
