I assisted someone in setting up Hobbit on a system that had selinux 
enabled,
and this was what I needed to do to get it to work correctly:

chcon -t httpd_sys_script_exec_t /usr/lib/hobbit/cgi-bin/*
chcon -t httpd_sys_script_exec_t /usr/lib/hobbit/cgi-secure/*
chcon -R -t httpd_sys_script_ro_t /var/lib/hobbit/rrd/

(besides usual file permissions issues).

I will try and see if I can ensure this isn't necessary (either setting 
the
contexts during the package build, or in a postinstall script) for my own
hobbit RPMS, if it works, I may make the packages available.

Regards,
Buchan
