The Hurd has the concept of a user who is not logged in. A fourth set of rwx
permissions. Those are set to r-x by default it seems. The right fix would
be to modify chmod etc to support those flags and make use of it.

(It's not a bug, it's a feature.)

Use "df /" or other pathes for other mount points. The decentralised design
of the Hurd makes it infeasible to have a central repository like mtab.
There may be a solution later, but currently no list of mounted partitions
is available, so you have to specify which one you want to check.

proc is by no means any standard in any way. There is the libps library if
you need to talk to the proc server. If you want to write a proc fs emulator
for linux binaries, go for it. It can be implemented as a translator :)
