It would to be nice to be able to turn off allocation of subuids/subgids in useradd while having /etc/subuid and /etc/subgid files.
Defining SUB_GID_COUNT=0 and SUB_UID_COUNT=0 in /etc/login.defs leads to the error message:

useradd: Can't get unique subordinate UID range
useradd: can't create subordinate user IDs

Thanks, that does look like a bug.

In addition to fixing that bug, it might be nice to have a --no-subuids --no-subgids option (maybe only a --no-subids, not sure anyone would ever want just one or the other).
