Comment # 7 on bug 1204956 from Michael Andres

Basically the current package cache is not designed to be shared. Even if the
repos on all hosts are configured identically, the current code is not prepared
for concurrent cache access. The risk for collisions may be small but it is
present.

A new implementation is on our whishlist, but ATM with a low priority.


Nevertheless I'll check if we can offer an easy tweak to prevent cleaning the
orphaned package caches. Technically there is no reason for doing it, but we
also had bugreports that we keep the package caches of deleted repos.

It might be as simple as touching a '.keep_orphaned' file in the package cache
topdir. It will however require that all clients run a recent libzpp.
