Initialize a mock chroot environment variable

[Anthony Joseph Messina]

Is it possible to initialize a mock chroot environment variable with the 
return from the evaulation of a simple script when calling a koji build?  
Something like:

/etc/mock/site-defaults.cfg:
config_opts['environment']['MYVAR'] =
"/usr/local/sbin/myscript.sh"

Where /usr/local/sbin/myscript.sh contains something like:
#!/usr/bin/bash
file="/tmp/$RANDOM.txt"
touch "$file" # Created outside the chroot
echo "$file"  # $file passed as the MYVAR environment variable 

If not, might you suggest another way of accomplishing this task?

Thanks in advance.  -A

Do you want to run /usr/local/sbin/myscript.sh inside the chroot or
outside of it? If outside, something like this should work -- the config
file is just plain Python code:

import os
config_opts['environment']['MYVAR'] = \
    os.popen("/usr/local/sbin/myscript.sh").read().strip()

If you want to run it inside the chroot, you can emit a chroot profile.d
script that does stuff, for example:

config_opts['files']['etc/profile.d/zz-mystuff.sh'] = """
MYVAR=$(/usr/local/sbin/myscript.sh)
"""
