pkg_chk replacement?

[Marcin Jessa <lists@xxxxxxxxx>]

Hi guys.

Is there any better solution for automatic package upgrade than
pkg_chk ?
The main problem with it is it deinstalles all upgrade candidates
before upgrading them.
So running pkg_chk -uvk will remove a bunch of packages first leaving
the server pretty much crippled for the time of compilation.

Cheers,
Marcin.
