>Description:
the etc/rc.d/sysctl script attempts to get the current value of a sysctl and skip setting it if it is already equal to the target value. if the value contains spaces the check fails and that line of sysctl.conf is skipped.
adding quotes around the check solves this.

example line to test:
dev.hdaa.0.nid5_config=as=15\ seq=0\ conn=None
