Hello, my Guix System is broken, and reverting to previous system generations

This segmentation fault is 'normal' (but indeed confusing):
https://codeberg.org/guix/guix/issues/3333

A filesystem check is also normal after a power failure.
Are there any other messages? (I personally would probably not be of
much further help though.)
