Re: knoppix-terminalserver doesn't work

[Klaus Knopper <debian-knoppix@knopper.net>]

Hello Werner,

Thanks for researching and finding the source of the bug. I had not much
time to look into it yet, but /etc/init looks wrong. Makes me wonder why
I ever used this path first place in the script. :-/

The idea behind this change was the possibility to circumvent the
sysvinit boot process, and start a single program as process 1 instead.
The fact that init= was not evaluated when running from an initramfs
prior to Knoppix 7.4.2, was (IMHO) a bug rather than a feature.

Thanks for your finding, I now fixed the path in
knoppix-terminalserver.sh and uploaded a new package to
debian-knoppix.alioth.debian.org from where people can pull updates for
knoppix-specific packages. It will be included in the next (probably
update/bugfix only) release.
