Arch Linux

Description:

Trying to add any module via e.g. *modprobe fat* yields

> modprobe: FATAL: Module fat not found in directory /lib/modules/4.6.1-2-ARCH

, which is obviously the wrong version number (the last two digits are flipped). According to [man modprobe](http://man7.org/linux/man-pages/man8/modprobe.8.html), modprobe looks up modules in */lib/modules/`uname -r`*. Invoking *uname -r* returns

> 4.6.1-2-ARCH

, which is wrong again. According to [this stackexchange post](http://unix.stackexchange.com/questions/136959/where-does-uname-get-its-information-from), uname reads a hardcoded C structure from the running kernel, populated in *sys/utsname.h* (see also [man 2 uname](http://man7.org/linux/man-pages/man2/uname.2.html)).

Since *uname*'s output includes the keyword *ARCH*, I don't think this is an upstream issue, but rather a packaging mistake.


Steps to reproduce:

1. Install *linux 4.6.2-1*
2. Run *modprobe* with an arbitrary module name, e.g. *modprobe fat*.
3. Run *uname -r*.
4. Observe how the output of the last command is subtly, but fatally wrong.
