****************************** SPECIAL WARNING: ******************************
20180528:
Support for token ring networks has been removed. If you
have "device token" in your kernel config you should remove
it. No device drivers supported token ring.
20180323:
makefs was modified to be able to tag ISO9660 El Torito boot catalog
entries as EFI instead of overloading the i386 tag as done previously.
