#
# This file collects definitions that are useful when using pkgsrc as an
# unprivileged (non-root) user. It is included automatically by the
# pkgsrc infrastructure.
#
# User-settable variables:
#
# UNPRIVILEGED
# Whether to build packages as unprivileged user.
#
# Default: (undefined)
# Possible: yes no
#
# UNPRIVILEGED_USER
# The user name (or numeric uid) that will be used to install
# files.
#
# Default: The user building the package
#
# UNPRIVILEGED_GROUP
# The group name (or numeric gid) that will be used to install
# files.
#
# Default: The primary group of the user building the package
#
# UNPRIVILEGED_GROUPS
# The group names that can be used to install files. Where a
# per-package custom group is declared that matches a group name
# in this variable, it will be left unmodified. Any per-package
# custom group not in this list will be forced to the value of
# UNPRIVILEGED_GROUP.
#
# Default: The complete group membership of the user building
# the package
#
# Package-settable variables:
#
# PKG_USERS_VARS
# A list of variables that hold bare user names, e.g APACHE_USER, etc.
#
# PKG_GROUPS_VARS
# A list of variables that hold bare group names, e.g UUCP_GROUP, etc.
#
# XXX: How can the user say that some of the packages shouldn't override
# the user and group names?
#
# PRIVILEGED_STAGES
# A list of phases (not stages) that are run as the privileged
# user. Some packages, when installed with just-in-time-su, leave
# temporary files in the working directory, so the "clean" phase
# must have enough priviledges to clean them up.
#
# Possible: clean
# Default: (undefined)
#
# === System-defined variables ===
#
# REAL_ROOT_USER
# The name of an omnipotent user account on the system.
#
# XXX: Why do we have this variable when it is set to ${ROOT_USER}
# anyway for unprivileged builds? Shouldn't packages that require
# such a user just fail in unprivileged mode?
# (See NOT_FOR_UNPRIVILEGED.)
#
# REAL_ROOT_GROUP
# The primary group of the REAL_ROOT_USER.
#
# ROOT_USER
# XXX: ???
#
# ROOT_GROUP
# The primary group of the ROOT_USER.
#
# BINOWN, BINGRP, GAMEOWN, GAMEGRP, MANOWN, MANGRP, SHAREOWN, SHAREGRP,
# DOCOWN, DOCGRP, BINMODE, NONBINMODE
# Ownership and permissions of the various types of files that are
# installed by the packages.
#
# XXX: What do we need all these different variables for? Wouldn't
# it be ok to install all files as ROOT_USER:ROOT_GROUP?
#
# PKG_CREATE_USERGROUP
# Since an unprivileged user normally cannot create other users
# and groups, this pkgsrc feature is disabled.
#
# XXX: This setting should be moved into pkg_add.
#
# PKG_REGISTER_SHELLS
# Since an unprivileged user normally cannot add entries to
# /etc/shells, this pkgsrc feature is disabled.
#
# XXX: See PKG_CREATE_USERGROUP
#
# TOOLS_PLATFORM.chown, TOOLS_PLATFORM.chgrp
# These tools cannot be used in their full extent by unprivileged
# users.
#
# XXX: chgrp may work for some groups.
#
# Keywords: unprivileged root override
