Simple guide to configuration without re-mastering

New page

==Quickstart==
Two options

* From the command line use "saveconfig".

* From KDE use the knoppix menu and find the "save configuration" item.

The system prompts you for what to save, and where to save it (choose from all the local disks and removable media that the system knows about). When you restart knoppix just add a boot parameter (see also [[Cheat Codes]] for more options). E.g.:

boot: knoppix myconfig=/mnt/sda1

Or, to scan all local disks:

boot: knoppix myconfig=scan

==Examples==
===Change default runlevel===
Just edit the initdefault line in /etc/inittab:

# The default runlevel
id:4:initdefault:

Then saveconfig.

Useful if you want to suppress the auto-start of the xsession.

===Start ssh on startup===

If you haven't used ssh yet, then start it up, to initialise the keys:

$ /etc/init.d/ssh start

Then add a line to /etc/inittab with the desired runlevels in the
second column:

# Start ssh on startup
ss:4:wait:/etc/init.d/ssh start

Then saveconfig.

Nice for people who want to use knoppix as a server and connect with
remote clients. Also for VMWare users where knoppix is the guest OS.

This is admittedly a bit of a hack, since the normal /etc/rc mechanism
would work, but would not be saved in the persistent configuration.
In this case we would simply add a symlink to rc4.d linking to
/etc/init.d/ssh.

===Add user accounts===

Just use /usr/sbin/useradd as normal, and then save the config.

===Mount user's home directories===

If you add user accounts then the new users will prefer to be able to
have a persistent home directory. This can be achieved by mounting
and linking during init. Create a script in /etc/init.d
(e.g. /etc/init.d/setup-homes) that mounts a local drive or image, and
links a directory there to /home/<uname>. Then run this script
automatically at start up by adding a line to /etc/inittab

# Mount user homes
uh:4:wait:/etc/init.d/setup-homes

Then saveconfig.

===Add more software===

Similar to the user home directory example, just install the software
on a local drive, and create a script to mount it on startup (and if
desired link it into standard path locations like /bin, /usr/bin). Then saveconfig.

==Pitfalls and problems==
===Symlinks are not saved===

The saved configuration only consists of true files, not symlinks,
hence the problem with /etc/rc mentioned above. (This is true at knoppix 3.6, please edit this page if things have changed.)

===Overwriting auto-generated files===

Certain files (e.g. /etc/fstab) are auto-generated by knoppix on
startup (mostly in /etc/init.d/knoppix-autoconfig), and then
overwritten from the saved configuration.

===Boot parameters===

You can't set boot parameters (a.k.a. [[Cheat Codes]]) except by
typing them at boot time. It is, however, probably the most trivial
re-mastering to change boot parameters.

===Language preferences===

Language preferences are always overridden at startup according to the
boot parameter lang= (see also [[Cheat Codes]]). Changes to
/etc/sysconfig/keyboard will go into the saved configuration, but are
always ignored.

===Don't use knoppix.sh===

Many forum posts are from users who have hacked knoppix.sh to change startup behaviour. This script is auto-generated by saveconfig every time you save the
configuration, so manual changes will be overwritten. Use init
instead.

==Behind the scenes==
The save config script actually saves all true files from /etc that
are missing or different from the distribution (at /KNOPPIX/etc).
