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

       /etc/subuid
           List of users subordinate user IDs.

       /proc/[pid]/uid_map
           Mapping of uids from one between user namespaces.
