Did it happen by default? Or did you modify an init script? (In reply to comment #3) > Did it happen by default? Or did you modify an init script? It happens by default We have allowed this in F18. Did you disable unconfined.pp module? I'm not sure, I think I may have disabled it to speed up some policies compiling. How can I check if it's disabled? semodule -l | grep unconfined Yes, I have it disabled:
# semodule -l | grep unconfined
> unconfined 3.3.0 Disabled
mgrepl lets add systemd_read_unit_files(initrc_t) Added.
