Hi John,
Yes, for the moment SAVFL 10.0.14 is the solution. The good news is that when SEP 12.1 RU5 is released in a couple months, there will at last be a managed SEP for Linux client. This will greatly ease the tasks of deploying policies, configurign reporting, etc.
I expect that the SEPFL clients will need to update their definitions from Internet sources or an internal LUA 2.x server, the same as SEP for Mac.
One important article to be aware of:
Symantec AntiVirus for Linux: Building the AutoProtect kernel modules fails on RHEL-based Linux releases 6.3 or newer

Hope this helps!
