Perhaps one could open a portage bug/feature request about it. eix-0.31.7 accepts both (=dev-qt/*-5.6* with PMS rules as well as the non-PMS =dev-qt/*-*5.6* [with string instead of PMS matching rules]).

Exactly, and that's why there needs to be some sort of place holder for
the file name.

The problem is that the file can be written to while it is being
examined when the examination is performed before it is rotated. That
can lead to false results of the examination.

Thanks, that sounds as if it will provide exactly what I'm looking for
:)

I think it's more a case of "you want it to be to solve this special problem you have", and perhaps the logrotate maintainer doesn't agree. -- Alan McKinnon alan.mckin...@gmail.com
