Where to find dmesg and /etc contents of specific system generation?

[Vladilen Kozin]

Hi guix.

Is it possible and where could I find contents of /etc for a specific
system generation. Ditto dmesg of the last boot of specific
generation? Not necessarily current generation though.

In a nutshell: I have a generation that boots and works fine, but
sadly I also have a generation that fails to boot. I'd like to debug
the issue by looking at its dmesg as far as it had gotten and also
checking its /etc/fstab and such seeing how the problem appears to be
mount related.

Thank you

I think if you type
guix system list-generations

you will see "canonical file name" which lists a path. inside there there is an etc directory that looks like the right one.

Hmmm.  I suppose you could try to make a guix system vm with that
configuration, and try to fire up the vm and see what happens...I'm not
certain how helpful that would be though.

I think guix may support connecting to a serial console, though I've
never tried it.

You're trying to run a server right?  How complicated is your config?
