useradd adds users. if the user already exists, naturally it won't be able to create it again.
usermod -a -G newgroup user The -a tells it to add the group instead of overwriting the previous group info.

The 'sys' group is not included in the list of secondary groups for this user.

Anybody? (1 Reply)

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.
