Re: DPKGPackageCheck() implementation.

[Russell Adams]

I've been testing the enclosed configuration for my network.

I figured this was on topic, but didn't require a module.

Basically I'm maintaining packages by editing the output from "dpkg
--get-selection" kept in a text file. This is imported with
UpdatePackageLists, and any missing packages installed via
DselectUpgrade.

I trigger these using timeclasses tied to a host.

It seems to work well so far.

I've based it on a post from 2003 by Thomas Glanzmann, see it at:

There are additional definable classes to trigger various package
management actions.
