Bug 370009 – sys-fs/udev error evaluating kernel version in /lib/udev/shell-compat-KV.sh for git vanilla kernel

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ingo Krabbe 2011-06-04 11:16:52 UTC]

I use to boot own git master vanilla kernel updates, which recently got a kernel release version string of x=$(uname -r)="2.6.39+".
This kernel version isn't stripped in the right way by the expression in
  /lib/udev/shell-compat-KV.sh +17
  local x=${1%%-*}
which cuts of anything after the first "-" in the release version string.

Reproducible: Always



Expected Results:  
What we actually want is a stripped version string consisting of digits and DOTs ".", i.e. "2.6.39" in our case.
so why not exchange line 17 with the expression of what we really want:
  local x=${1%%[^.0-9]*}
which cuts off anything from the first character that isn't a DIGIT or a DOT.
If you want to allow spaces too, you might, but they are not needed here.
