OK.  My guess is that there was maybe a transient error with your hard
disk, which led the kernel to remount the root file system read-only,
which in turn led to the failure of various programs, including
‘guix-daemon’.

I’m closing the bug, but do reopen it if you have reasons to suspect a bug!

Thanks,
