Hello,
‘guix system roll-back’ and ‘switch-generation’ don’t reload servicesand don’t run activation scripts like ‘guix system reconfigure’ does.Indeed:
Toggle snippet (12 lines)(define (switch-to-system-generation store spec) "Switch the system profile to the generation specified by SPEC, andre-install bootloader with a configuration file that uses the specified systemgeneration 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))))

Hello Guix,
To summarise the whole thread, in addition to the main issue explainedin the title “'guix system switch-generation' does not reload Shepherdservices“ there are 2 other issues talked about.
1. The activation script isn't executed by 'guix system switch-generation', which is fixed in df138dc20858725b90ed77be85f3318cbe1be73a and later.2. The activation process isn't exclusivly build during the system building process, whihc may the leave the system in half-hazard state if the building taking place during the activation fail.
The second side issue should proablby have it's own bug report sinceit's still present and we should keep that bug report only for the lackof reloading of shepherd service when using 'guix systemswitch-generation' (or 'roll-back').
Cheers,- Brice
