Thanks!  I tried this change again and now it seems the newly-added filesystem
won't be automatically mounted.

Another concern I have is, with /run and /var/run unified,
‘guix system roll-back’ and ‘guix system switch-generation’ can't finish the
activation stage because of the error handling in dbus-activation from previous
generations.

--8<---------------cut here---------------start------------->8---
$ guix system describe
Generation 7	Dec 20 2024 23:10:05	(current)
[...]
$ sudo guix system roll-back
[...]
switched from generation 7 to 6
[...]
guix system: error: rmdir: Directory not empty
$ guix system describe
Generation 6	Dec 20 2024 22:57:19	(current)
--8<---------------cut here---------------end--------------->8---

Do we have a way to fix this?
