For any cuirass-curious readers, I want to say I deployed it on Linode a
week ago and its been one of the most "just works" out-of-the-box tools in
the guix arsenal that I've encountered. It was really easy and painless to
get going, and makes "pinning" milestone system & profile generations a
breeze so that you always have substitutes available for them. This has
sped up my guix workflow tremendously, as I'm able to just commit push,
branch off, try other ideas, push, review past results and keep moving,
instead of getting distracted by checking the news or what have you.

 The remote-server sometimes stops allocating builds to workers though, but
I just restart the server and its fine.

Feels like proper boutique gear, too ;)
