NAME

acct-user.eclass - Eclass used to create and maintain a single user entry

DESCRIPTION

This eclass represents and creates a single user entry. The name of the user is derived from ${PN}, while (preferred) UID needs to be specified via ACCT_USER_ID. Additional variables are provided to override the default home directory, shell and add group membership. Packages needing the user in question should depend on the package providing it.

The ebuild needs to call acct-user_add_deps after specifying ACCT_USER_GROUPS.

Example: If your package needs user 'foo' belonging to same-named group, you create 'acct-user/foo' package and add an ebuild with the following contents:

EAPI=7
inherit acct-user
ACCT_USER_ID=200
ACCT_USER_GROUPS=( foo )
acct-user_add_deps

Then you add appropriate dependency to your package. The dependency type(s) should be: - DEPEND (+ RDEPEND) if the user is already needed at build time, - RDEPEND if it is needed at install time (e.g. you 'fowners' files
in pkg_preinst) or run time.

SUPPORTED EAPIS

FUNCTIONS

acct-user_add_deps: Generate appropriate RDEPEND from ACCT_USER_GROUPS. This must be called if ACCT_USER_GROUPS are set.
acct-user_pkg_pretend: Performs sanity checks for correct eclass usage, and early-checks whether requested UID can be enforced.
acct-user_src_install: Installs a keep-file into the user's home directory to ensure it is owned by the package, and sysusers.d file.
acct-user_pkg_preinst: Creates the user if it does not exist yet. Sets permissions of the home directory in install image.
acct-user_pkg_postinst: Updates user properties if necessary. This needs to be done after new home directory is installed.
acct-user_pkg_prerm: Ensures that the user account is locked out when it is removed.

ECLASS VARIABLES

ACCT_USER_ID (REQUIRED): Preferred UID for the new user. This variable is obligatory, and its value must be unique across all user packages.
Overlays should set this to -1 to dynamically allocate UID. Using -1 in ::gentoo is prohibited by policy.
ACCT_USER_ENFORCE_ID: If set to a non-null value, the eclass will require the user to have specified UID. If the user already exists with another UID, or the UID is taken by another user, the install will fail.
ACCT_USER_SHELL ?= -1: The shell to use for the user. If not specified, a 'nologin' variant for the system is used.
ACCT_USER_HOME ?= /dev/null: The home directory for the user. If not specified, /dev/null is used. The directory will be created with appropriate permissions if it does not exist. When updating, existing home directory will not be moved.
ACCT_USER_HOME_OWNER: The ownership to use for the home directory, in chown ([user][:group]) syntax. Defaults to the newly created user, and its primary group.
ACCT_USER_HOME_PERMS ?= 0755: The permissions to use for the home directory, in chmod (octal or verbose) form.
ACCT_USER_GROUPS (REQUIRED): List of groups the user should belong to. This must be a bash array. The first group specified is the user's primary group, while the remaining groups (if any) become supplementary groups.
