This issue has been reported by a number of users on IRC.  I think the
problem is that the the #:file-creation-mask keyword requires support
from the running Shepherd, which may not have it yet.  I think we should
revert commit 4c0cc7bed3de2c0e2d3a6e95b88693941e839eec until we find a
smooth upgrade path.  Can you try it and push if that fixes guix deploy?
