I didn't mean to imply you enabled it intentionally.  In fact it looks
like the inode tracking in IMA is always on once it's compiled in, which
totally defeats the purpose of doing it's on iternal inode tracking
instead of bloating the inode what they originally proposed.  IMA really
needs a kernel parameter to only enabled this crap when people actually
use it.

And whoever turned it on in Fedora needs some serious wahcking.
