+
+There is no `/etc/mtab` (due to dynamic translator startup, its content is hard
+to define actually, see
+[[the mtab GSoC project idea|community/gsoc/project_ideas/mtab]]),
+so just running `df` will yield the following error.
+
+ df: cannot read table of mounted file systems
+
+Pass `df` a path like `df /` or `df ./` to see the disk usage of that particular
+file system.

+There is no `dmesg` command, since the kernel does not keep a buffer of its

+ $ halt

+[[!meta title="Why is `/usr' a symbolic link to `.'?"]]
+
+The distinction between `/` and `/usr` has historical reasons. Back when [[Unix]]
+systems were booted from two tapes, a small root tape and a big user tape.
+Today, we like to use different partitions for these two spaces. The Hurd
+throws this historical garbage away. We think that we have found a more
+flexible solution called union filesystems, which allow to create virtual
+filesystems which are the union of several other filesystems. However, support
+for union filesystems is still in early development.

+# IRC, freenode, #hurd, 2012-02-01
+
+ <marcusb> I remember the time when we had a /usr symlink. Now fedora 17
+ will move / to /usr and have /foo symlinks. :)
+ <marcusb> braunr:
+ http://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge
+ <marcusb> braunr: fedora and others are merging /bin, /sbin and some other
+ into /usr
+ <marcusb> braunr: back in 1998 we tried for two years or so to have /usr ->
+ .. in Debian GNU/Hurd, but eventually we gave up on it, because it broke
+ some stuff
+ <gnu_srs> marcusb: Hi, which one is better (in your opinion): / or /usr?
+ <marcusb> gnu_srs: fedora says that using /usr allows better separation of
+ distribution files and machine-local files
+ <braunr> marcusb: won't it break remote /usr ?
+ <marcusb> so you can atomically mount the OS files to /usr
+ <marcusb> gnu_srs: but in the end, it's a wash
+ <marcusb> personally, I think every package should get its own directory
+ <braunr> marcusb: what PATH then ?
+ <marcusb> braunr: well, I guess you'd want to assemble a union filesystem
+ for a POSIX shell
+ <braunr> marcusb: i don't see what you mean :/
+ <braunr> ah this comes from Lennart Poettering
+ <marcusb> braunr: check out for example how http://nixos.org/ does it
+ <manuel> braunr: something like, union /package1/bin /package2/bin
+ /package3/bin for /bin, /package1/lib /package2/lib /package3/lib for
+ /lib, etc. I guess
+ <braunr> manuel: would that scale well ?
+ <marcusb> the idea that there is only one correct binary for each program
+ with the name foo is noble, but a complete illusion that hides the
+ complexity of the actual configuration management task
+ <braunr> marcusb: right
