>From your log, the format didn't even took place, as it is the following
step from run-partitioning-page (at gnu/installer/newt/partition.scm),
but it was writing the partitions to the disk.  I think this comment
from free-parted (at gnu/installer/parted.scm) tells the same problem
you're hitting:

----------------------------------8<--------------------------------------
;; XXX: Formatting and further operations on disk partition table may fail

---------------------------------->8--------------------------------------

Nonetheless, we're only waiting 1 second + processing time to timeout
the lookup for EBUSY at 'with-delay-device-in-use?'.  Should we extend
that timeout?  I don't think waiting even minutes at this stage would be
a big issue, as formatting an encrypted partition may take hours and
will be performed just after that.

WDYT?

Happy hacking!
