Version 11.4, but possibly all earlier -- YAST

Hi.

I was added this line to my ~/.profile file :


export GREP_OPTIONS="--line-number"

Yesterday, I have decided to upgrade my system to version 11.4 M6 from 11.4 M5 .
What I realize, Yast is caused by this environment variable - it doesn’t remove it at startup.

Because I have upgraded a lot of packages, Yast have written to /etc/passwd, /etc/groups, /etc/shadow
After upgrade one line from /etc/passwd looks like this:
19:root:x:0:0:root:/root:/bin/bash

In fact, first I try to do is reinstall of pam modules, because /etc/passwd, etc. files exist.
I have miss a few hours today to repair my system.

Couldn’t Yast remove all unnecessary environment variables?

I still don’t reconfigure/fix grub, so I used grub command line to start my system all of time.
