The nice thing about poudriere is that it doesn't affect the running
system. The act of creating the package repo is completely separate from
the act of installing packages. The two steps can be done on a single
system, or on separate systems.
During the creation of the package repo via poudriere, nothing on the
client system is affected; nothing is installed, nothing is uninstalled.
One can continue to use the system, which is great for desktops and
critical servers alike.
If there's an issue compiling a port in the middle of a long dependency
chain in poudriere, the process stops and you work to fix it. Nothing you
do at this point affects any of the client(s). If you can't get it fixed,
you don't have to worry about rolling back versions on the client(s) to get
things back to a working state.
Only once you have everything compiled and packaged up do you worry about
the client system(s). And there, the pkg system takes over and handles
everything. It's pretty much a "everything works or nothing gets
installed" process at that time (with very few corner cases that break
It's not bulletproof, but it's a lot safer than compiling things on the
live system where some compiler bits are picked up from the ports build
tree, while other bits are picked up from the live filesystem, while some
things are auto-detected based on other installed ports, while some things
are skipped for the same reason, etc.
Will there be situations where you want to compile directly on the client?
Maybe. Will there be many people that need that against all other
options? Not really.

I used to love compiling everything on my home systems and work systems.
Then KDE upgrades kept leaving me with a broken system due to enabling some
esoteric OPTIONS that I thought I needed and portmaster would fail in the
middle of the umpteen-level-deep dependency chain. I could usually get
things back to a working, upgraded state, but that usually left me without
a working GUI for 2-4 days. The introduction of pkg has alleviated me of
that need. :) I don't even have /usr/ports installed on my home or work
After ending up with a broken server at work for the same reason I switched
those to using pkg only. I played with poudriere back in the early days
and it was easy to work with. But I found myself setting fewer and fewer
custom OPTIONS so the need for it diminished with time. Debated playing
with it at work to get a custom OpenSSH package (for NONE encryption), but
I found other ways to do the same.
