NAME

       newuidmap - set the uid mapping of a user namespace

SYNOPSIS

       newuidmap pid uid loweruid count [uid loweruid count [ ... ]]

DESCRIPTION

       The newuidmap sets /proc/[pid]/uid_map based on it's command line arguments and the uids allowed in
       /etc/subuid.

OPTIONS

       There currently are no options to the newuidmap command.

NOTE

       The only restriction placed on the login shell is that the command name must be listed in /etc/shells,
       unless the invoker is the superuser, and then any value may be added. An account with a restricted login
       shell may not change her login shell. For this reason, placing /bin/rsh in /etc/shells is discouraged
       since accidentally changing to a restricted shell would prevent the user from ever changing her login
       shell back to its original value.

FILES

           List of users subordinate user IDs.

       /proc/[pid]/uid_map
