Hmm, IMHO that's just tampering with the symptoms of the
underlying problem. Things to consider:
- rpm should not use the nscd of the "outer" system, but glibc
caches the connection
- it should also not use the outer nss configuration, this is
also cached
At some point after looking at the glibc sources I gave up and
implemented a tiny password/group parser in rpm. See:
http://www.mail-archive.com/rpm-maint@lists.rpm.org/msg01759.html
OTOG glibc may have changed meanwhile...
Cheers,
Michael.
