Hello,
‘guix system roll-back’ and ‘switch-generation’ don’t reload services
and don’t run activation scripts like ‘guix system reconfigure’ does.
Indeed:
--8<---------------cut here---------------start------------->8---
(define (switch-to-system-generation store spec)
"Switch the system profile to the generation specified by SPEC, and
re-install bootloader with a configuration file that uses the specified system
generation as its default entry. STORE is an open connection to the store."
(let ((number (relative-generation-spec->number %system-profile spec)))
(if number
(begin
(reinstall-bootloader store number)
(switch-to-generation* %system-profile number))
(leave (G_ "cannot switch to system generation '~a'~%") spec))))
--8<---------------cut here---------------end--------------->8---
Ludo’.
