Before rebooting, I had:
--8<---cut here---start->8---
$ ls -l /run/{current,booted}-system
lrwxrwxrwx 1 root root 33 Nov 2 16:06 /run/booted-system ->
/var/guix/profiles/system-68-link
lrwxrwxrwx 1 root root 50 Feb 21 01:34 /run/current-system ->
/gnu/store
/run/booted-system is not protected from GC. Here’s what I observed on
a machine with unattended upgrades (which includes automatic removal of
old system generations):
--8<---cut here---start->8---
~$ ls -l /run/booted-system
lrwxrwxrwx 1 root root 33 Nov 2 1
