Applying patches #38462 and #38468 and changing the file system
definition to the following should allow you to mount the root file
system with the 'lazytime' option:
--8<---------------cut here---------------start------------->8---
(file-system
(device (file-system-label "GUIX"))
(mount-point "/")
(flags '(lazy-time))
(options "compress")
(type "btrfs"))
--8<---------------cut here---------------end--------------->8---
