The last command is how the system really works; your current
directory (as it is known by the kernel or by the proc server) is
/linux/home/ogi/deb, and the parent of that directory (as recorded
inside the filesystem) is /linux/home/ogi, or /linux/home/ogi/deb/..
Those two are two different names (hard links) to the same directory.
cd .. works differently, because it is a builtin command of your
shell, which keeps track of your previous cd:s. It translates .. to
your internally, lying to you in order to be nice and friendly.
I think both bash and some csh-variants have this interesting feature.
And it doesn't have much to do with the Hurd, those shells work just
the same on any Un*x system.
