I can/will give you a cron script then.
(aside)
Because RPM uses POPT its quite feasible to retrofit a
--rebuildhrmib
option to all versions of rpm, even legacy. Then there
is no cron "script" per-se whatsoever, and RPM (including
legacy versions) is responsible for maintaining the
"installed software base" and net-snmp is responsible for
reporting that info through the HR-MIB.
Presumably sysadmin's can arrange for a cron script to invoke
rpm --rebuildhrmib
on whatever time scale they choose important to their own reporting needs,
including invoking "rpm --rebuildhrmib" at the end of any upgrade operation.
And there's finally a clean separation of responsibilities without the rather
difficult -lrpm and Berkeley DB locking deadly embrace.
