Hi! I have about 10 machines running mdk 7.2 (updated from 7.1) with RPM version 3.0.5 . In one of this machines I try to install rpm 4.0 from mdk 8, but it needs glibc 2.2. So I update almost everything needed to install rpm (using rpm binaries from mdk 8 cds and recompiling some src.rpm) ... When I check that all the dependencies where ok... I proceed to rpm -Uhv rpm...... it was ok apparently..... what I found after the install was that rpm -qa shows that nothing is installed. :( Looking around I found out that the rpm database change his name or something like that........ files with names: Packages Providename Requirename etc.... in /var/lib/rpm after the upgrade have size 0. I need to update the other machines...... (to keep them in sync).... but I want to know if there is a way to keep the database in the upgrade of the rpm package from ver.3 to version 4. I couldn't make a fresh install to mdk 8. (I couldn't shutdown all the machines for an upgrade). ALF
