I tried to upgrade my headless server running GuixSD from to HD to SSD.

First I shot myself in the foot doing 'guix init' on the SSD. Possibly
by labeling the SSD root using the same label as the system HD root, or
maybe I miss-specified the bootloader device?

Anyway, to dig myself out, I switched to a 2nd server running
Guix/Debian and ...

- reinstalled GuixSD to the 1st server's HD, see
  "c06system.scm.log". This runs fine back in the 1st server.

- I did a near-identical install to a SSD (Kingston ssdnow300), see
  "c06system-ssd.scm.log". If installed on the 1st server this shows
  Guix welcome screen, loads the keyboard & mouse drivers, then hangs
  showing:

  "clocksource: Switched to clocksource tsc"

So to summarize, ~identical install on HD runs fine, install on SSD
hangs.

Please see attached logs. - George
