SELinux transition between hostname_t and initrc_tmp_t differs

Issue

If you are starting a service with no file contexts definitions on the binaries, then the process is running in the initrc_t domain.

• If this process then executes a shellscript using bash it can execute the "hostname" command without problems.

• But if this process executes a ksh script then SELinux blocks "hostname" commands in this shell script.
