yep.
$ rpm -q yum
yum-3.2.22-26.el5
and after quick update to
3.2.22-37.el5
same picture...

you got me there. What do you mean? So far I'm stuck trying to figure out what
the hdr['tag'] should include - from what I've seen _populatePrco() is
supposed to do exactly that, but apparently it doesn't.
BTW, full traceback is:
0 packages excluded due to repository protections

thus the intent to go as "generic" as I can get away with.

tmprepo is where I've got the "inspiration" but turned out it was creating
temp files on a disk (in other words being a bit "hackish"). CPacMan repos
should be aggregated with cpacman_yum plugin and provide "unified" view even
through packages themselves are sprinkled around the filesystem. In our use-
case we use Yum as an "engine" and we have several people attempting to run
transactions at the same time (those push packages to remote machines rather
than install locally) so temp files don't look as tempting ;)
