Besides selinux, check also the environment, the user and the actual
shell. Usually cron jobs and init are **very** different environment
(and sometimes shells), compared to interactive ones. I've seen users
wasting dozens of hours trying to chase similar issues, which were all
trivially fixed sourcing a couple of dotfiles before calling (or
withing) the script.

HTH,
