[Patch] Bashism in startkde

[Armin Berres]

Heyya,

Debian and Ubuntu both want to support to use something else but
/bin/bash as /bin/sh. Therefore it is required, that all scripts whith
"#!/bin/sh" contain no bash specific code, but just POSIX features.

In startkde §$UID§ is used, which is bash specific. I propose the
following patch:

|Index: kdebase/workspace/startkde.cmake
|===================================================================
|--- kdebase/workspace/startkde.cmake    (revision 975766)
|+++ kdebase/workspace/startkde.cmake    (working copy)

| export KDE_SESSION_VERSION

|
|-KDE_SESSION_UID=$UID
|+KDE_SESSION_UID=$(id -ru)
| export KDE_SESSION_UID
|
| # We set LD_BIND_NOW to increase the efficiency of kdeinit.

The patch should be safe, but as this is startkde I want you to give me
a go first, before I commit.

Greetings,
Armin
