When using volumes, does Splunk count only index files or others too?

Question regarding 4.2+'s abililty to put a maxVolumeDataSizeMB on an arbitrary path, call it a volume, and put indexes in it.

I have some indexes at /data/indexes and also my syslog server logs to /data/logs.

If I set my index volume to be /data, will Splunk include the syslog logs in the volume size so I will never overrun my disk space? (If syslog data explodes for a few days, I would rather have old index buckets deleted than run against a disk space limit and stop accepting new data!)

According to gkanapathy, ONLY splunk indexes are counted, not other files that may be in the volume.
