Yes, it does. The number of actual configuration lines is much
smaller of course - probably 1/5th of the total.
My point wasn't so much that this was an inordinate number of 32-bit
packages, given my list of installed packages. It was more about the
fact that on a system that I'm trying to keep fairly minimal other
than my explicit preferences I end up with a huge config file that
tends to mix my preferences with a lot of stuff that exists solely to
satisfy the depgraph. It would be like sticking every package I
install in my world set.
There are some ways around this which I'll probably get around to on a
rainy day:
1. Take better advantage of the fact that package.use can be a
directory and have several files. The 32-bit flags would go in their
own file. Autounmask goes in a separate file with a z at the start of
the name and the intent is that lines in this file get moved to the
appropriate files. Then from time to time the 32-bit flags can be
deleted and re-created to keep them minimal as installed packages
change.
2. What I'd really like to get to is a point where all my systems are
defined by ansible configs or the like. I've already started
container-izing many of my services to cut down on interactions - this
way when I do random package updates I'm not dealing with mysql
breaking or apache or whatever. However, this increases the amount of
updating I have to do, and I'd like to bring that back down using a
tool like ansible.
