The RESTEASY_LIB variable is currently defined in /etc/pki/pki.conf:

# RESTEasy library
RESTEASY_LIB=/usr/share/java/resteasy

The variable should be moved into /usr/share/pki/etc/pki.conf where all other defaults are defined (e.g. JNI_JAR_DIR, future TLS settings), and customized at build time based on the target platform.

The /etc/pki/pki.conf should be left empty with just a comment similar to this:

# User-defined overrides go here.
# Defaults are in /usr/share/pki/etc/pki.conf.

Applications should read both pki.conf as shell script as follows:
1. source /usr/share/pki/etc/pki.conf
2. source /etc/pki/pki.conf (overriding variables defined earlier)
3. read the variable

In Python the variable can be read as follows:

value = subprocess.check_output(
    '. /usr/share/pki/etc/pki.conf && . /etc/pki/pki.conf && echo $RESTEASY_LIB',
    shell=True)
resteasy_lib = str(value).strip()

An upgrade script is needed to remove the variable from existing /etc/pki/pki.conf.

Proposed milestone: 10.3
