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:

• login name
• numerical subordinate group ID
• 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.
