# +DIRS - reference-counted directory management script
|
|
#
|
|
# Usage: ./+DIRS ADD|REMOVE|PERMS [metadatadir]
|
|
# ./+DIRS CHECK-ADD|CHECK-REMOVE|CHECK-PERMS [metadatadir]
|
|
#
|
|
# This script supports two actions, ADD and REMOVE, that will add or
|
|
# remove the directories needed by the package associated with
|
|
# <metadatadir>. The CHECK-ADD action will check whether any directories
|
|
# needed by the package are missing, and print an informative message
|
|
# noting those directories. The CHECK-REMOVE action will check whether
|
|
# any directories needed by the package still exist, and print an
|
|
# informative message noting those directories. The CHECK-ADD and
|
|
# CHECK-REMOVE actions return non-zero if they detect either missing
|
|
# or existing directories, respectively. The PERMS action will correct
|
|
# any ownership or permission discrepancies between the existing
|
|
# directories and the data in this script, and the CHECK-PERMS action
|
|
# will check whether any directories have the wrong ownership or
|
|
# permission and print an informative message noting those directories.
|
|
# The CHECK-PERMS action will return non-zero if it detects directories
|
|
# with wrong ownership or permissions.
|
|
#
|
|
# Lines starting with "# DIR: " are data read by this script that
|
|
# name the directories that this package requires to exist to function
|
|
# correctly, e.g.
|
|
#
|
|
# # DIR: /etc/foo m
|
|
# # DIR: /var/log/foo/tmp mo 0700 foo-user foo-group
|
|
# # DIR: share/foo-plugins fm
|
|
#
|
|
# For each DIR entry, if the directory path is relative, then it is taken
|
|
# to be relative to ${PKG_PREFIX}.
|
|
#
|
|
# The second field in each DIR entry is a set of flags with the following
|
|
# meanings:
|
|
#
|
|
# f ignore ${PKG_CONFIG}
|
|
# m create (make) the directory when ADDing
|
|
# o directory is owned by the package
