Good suggestion, but it's too late in the release cycle, even for
changes as trivial as this. A week ago it might have been possible.
It's worth noting that I've found the union filesystem to be quite
usable for certain configurations. I'm using it, and the only bug I
regularly trip over is the "panic during shutdown if cwd is inside a
union", which is easy to work around, but then I don't let hostile
users onto my systems..
Anyhow, I'm going to put some effort into fixing these for 1.5; for
instance, the vn_isunder() routine I added in 1.4 will allow 3645 to
be fixed in the kernel (where the fix belongs); the more recently
reported denial of service is not so straightforward to fix, though.
