5# absolute-symlink.sh - check for absolute symlinks on a FreeBSD system
6#
7# The purpose of this script is to detect absolute symlinks on
8# a machine, e.g.:
9#
10#    /etc/localtime -> /usr/share/zoneinfo/UTC
11#
12# Some of these absolute symbolic links can be created intentionally,
13# but it is usually better to use relative symlinks.
14#
15# You can run the script after `make installworld', or any other
16# make targets thats installs files.
17#
18# You can also check your local ports with:
19#
20#   env ABSOLUTE_SYMLINK_DIRS=/usr/local ./absolute-symlink.sh
