yum question

[bruce]

hey guys.


i can do a yum list installed

and i get a list of the installed packages for the local system.

However, I have no idea where this data is coming from!!!

is it coming from the
 /var/lib/rpm ,
/var//lib/yum/yumdb

or perhaps somewhere else??

is there a switch I could use to change the db, or to point to a
different yumdb/dir?

IE, I've got a drive from a separate/older system that I'd like to
mount/examine to see what packages where installed with yum on that
drive...

the "installroot" switch appears to be used to chroot into a separate
location for the yum.repos.d" - but I could be wrong..

thanks
