This script needs to be rewritten to follow the coding style / best
practices of package/busybox/S01syslogd, which is our reference init
script.

Do we need to check if it's available ? Isn't selinuxenabled one of the
dependencies of this package anyway ?

Why 7 ?

Useless, init scripts in Buildroot are executed as root.

Please drop these checks as well.

Follow the coding style of package/busybox/S01syslogd here.

We don't have any condrestart target in any other script.
