I'm seeing problems on RHEL7 with lvm2-activation-generator that are
coming from recent changes to put systemd-fstab-generator into it's
own domain. I resolved the issues by creaing this generator attribute
to grant common generator permissions and move all generators into
a single systemd_generator_t domain.
Then setup specific types for the following generators:
lvm2-activation-generator - needs to read lvm2 config
systemd-sysv-generator - needs to read stuff in init_t that other generators don't.
systemd-efi-boot-generator - needs to read stuff on the EFI boot partition labeled boot_t
For fstab generator allow it to write /sys

Only for services that already have a named init script.
Add rules to init_startstop_service(), with conditional arg until
all of refpolicy-contrib callers are updated.
