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
