Ok, am I weird or does this make no sense? To pin an #ostree deployment in #fedora #atomic desktop you use e.g.
sudo ostree* admin pin 0
Naively, I always think it should be
sudo ostree admin unpin 0
to unpin it again. But no. My sweat summer child. Why, it's *obviously*:
sudo ostree admin pin --unpin 0
(I kinda get why it is that but I will never be able to remember that.)
*Why not rpm-ostree? So many questions.
