You see the "oops" in your suggestion, correct? The group on one system is listed as "nobody" so ls -nd is going to show the gid (99) for nobody. On the other system, it's going to show the gid for the correct group. So they will never match until I get this fixed.

subgid

SUBGID(5)						   File Formats and Conversions 						 SUBGID(5)

NAME

       subgid - the subordinate gid file

DESCRIPTION

       Each line in /etc/subgid contains a user name and a range of subordinate group ids that user is allowed to use. This is specified with
       three fields delimited by colons (":"). These fields are:

       o   login name or UID

       o   numerical subordinate group ID

       o   numerical subordinate group ID count

       This file specifies the group IDs that ordinary users can use, with the newgidmap command, to configure gid mapping in a user namespace.

       Multiple ranges may be specified per user.

       When large number of entries (10000-100000 or more) are defined in /etc/subgid, parsing performance penalty will become noticeable. In this
       case it is recommended to use UIDs instead of login names. Benchmarks have shown speed-ups up to 20x.

FILES

       /etc/subgid
	   Per user subordinate group IDs.

       /etc/subgid-
	   Backup file for /etc/subgid.

SEE ALSO

       login.defs(5), newgidmap(1), newuidmap(1), newusers(8), subuid(5), useradd(8), userdel(8), usermod(8), user_namespaces(7).
