Subject: reverted grml-quickconfig: no more unnecessary wakeups
X-Git-Tag: 1.0.25~2
X-Git-Url: http://git.grml.org/?p=grml-scripts.git;a=commitdiff_plain;h=5577c0a475e68830c1cdccf5abbcb5b45286763a

reverted grml-quickconfig: no more unnecessary wakeups

Term::ReadKey seems to be buggy, the normal blocking call ReadKey(0) is not
blocking anymore after returning from an grml-x started through
grml-quickconfig.
