;;; This module provides "activation" helpers.  Activation is the process that
;;; consists in setting up system-wide files and directories so that an
;;; 'operating-system' configuration becomes active.

(define %skeleton-directory
  ;; Directory containing skeleton files for new accounts.
  ;; Note: keep the trailing '/' so that 'scandir' enters it.

Additionally, verify no component of DIRECTORY is a symbolic link,
without TOCTTOU races.  However, if OWNER differs from the the current
(process) uid/gid, there is a small window in which DIRECTORY is set to the
current (process) uid/gid instead of OWNER.  This is not expected to be
a problem in practice.

The permission bits and owner of DIRECTORY are set to BITS and OWNER.
Anything above DIRECTORY that already exists keeps
its old owner and bits.  For components that do not exist yet, the owner
and bits are set according to the default behaviour of 'mkdir'."
