Anyone taking a brief glance at the kernel options won't
notice that the union filesystem has problems until too late.
"file-system UNION # union file system"
"file-system UNION # union file system. (unstable, see options(4))"
In each kernel config file which has it.
Probably a good idea to put a more descriptive blurb in the options
man page. Maybe even in the bugs section of the mount_union page.
LFS should probably have something like this too.

+ The union file system has some significant locking problems. Use this
+ filesystem at your own risk. If you do decide to use it it would be best
+ to avoid allowing several processes to access both layers at the same time.
