What's the status on this (for mainline)?  I regard the link (both
symlink and hard link) and FIFO restrictions as a priority, compared to
some other things we'll be working on.  (In general, I want us to have a
full set of whatever was in 2.4.x-ow merged sooner rather than later.)

Thanks,

Alexander
