Yes, but as the comment in the source says, the goal is to be able to boot at
all, not be perfect.
So basically we could assume that if a previous system generation has used a
bootloader [name] (and we can still apparently run guix commands) then that
bootloader actually could boot that system, and presumably can boot it again if
we installed it now.
Might make sense to use the newest generation possible for that. (I think even
if you used the boot menu or guix system switch-generation, the newest
generation would still be present, just not current; so if that used the
bootloader name of the newest generation that exists we might be safe)
All this complication is just because we don't have the file name of the os
configuration (/etc/config.scm) in guix system delete-generations. What about
us just requiring it from the user and then installing the bootloader&config
that is specified there? That would be a lot less magical--it basically would
do the same that guix system reconfigure does now, then.
(What about guix system switch-generation? What does it do regarding
bootloader installation? *mumbles* *checks* Aha, it also only installs the
bootloader configuration)
guix/scripts/system.scm says:
> (bootloader (lookup-bootloader-by-name (system-bootloader-name)))
What is that (system-bootloader-name) magical parameterless call? Which
generation does that use? *shakes head*
Our source code there totally could use some more comments...
