Please can you specify how did you then installed Guix on your system?

Can you please try using uuid instead of file-system-label?

Yes, I did it on milano-guix-1 build machine (and I'm almost sure I'm
not the only one around):
That machine configuration is here:
http://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/milano-guix-1.scm
I initially installed on a RAID1 (both data and metadata) btrfs volume
using two disk partitions, with manual installation method, and it
worked; lately I added 4 more disks (whole disks) and converted the
volume to RAID10

Can you please provide a step-by-step report of what you are doing when
installing, maybe a review could reveal something wrong... or probably a
Guix bug :-)
Thanks for reporting!
Happy Guix! Gio'.
