Oh, that's right: usr and creat. How could I forget.

I use /debug but it's not too late to change. Fedora does not ship it yet,
so I don't think we have an institutional opinion about it.

Personally, I'm against the doubles to prevent issues with the mounting
order on boot, but that's rather weak. The /dev can be specially managed
and I'm concerned with people running find(1) on it. The /proc sounds
better, but mounting anything under /proc requires a kernel component
to create a directory, does it not?

[root@lembas root]# mount -t debugfs any /proc/debug
mount: mount point /proc/debug does not exist
[root@lembas root]# mkdir /proc/debug
mkdir: cannot create directory `/proc/debug': No such file or directory
[root@lembas root]#
