any hint what is the fastest method to find out which packages I can drop? actually all kde, x11 stuff etc...

In general, yes you can remove all the X11 & KDE packages. The removal of packages has been discussed in the past. I hope these are useful.

I have made some remasterings with menu based scripts according UndeScores's how-to and everything seems fine!

Anyhow, I have some problems as seen in .xsession-errors:

Code:

I have used Knoppix 3.8.1 but have changed in /etc/apt/apt.conf "testing" to "sarge", and have updated everyting with 'apt-get dist-upgrade'.

I have changed owner of /tmp/.ICE.unix to root as should:

Code:

chown root:root /tmp/.ICE-unix chmod 1777 /tmp/.ICE-unix

but anyhow I got _IceTransmkdir: Owner of /tmp/.ICE-unix should be set to root . What should be changed in remastering scripts so that owner and permissions are also OK in CD? I think that this and those other errors are not fatal but slows down starting KDE.

Btw, I had also problems with KMIx which started automatically to the desktop (I would like it to stay in launch panel only). I just changed K menu -> Control Center -> KDE Components -> Session Manager to start always a new session when logging in. Is this OK? It really works!

Hi,

I'm trying remastering kernel Knoppix 3.8.2, and I have a problem with UnionFS, I think. When I boot my iso, I see an error message over "CANNOT unite ramdisk" or something like that. Does anybody know to solve this problem? Have I to replace this module too? In "Knoppix custom kernel howto" I didn´t see anything about it.

I had the same problem with Knoppix 3.9, but I supposed the reason was a buggy UnionFS, but now I think I´m doing something wrong

Best regards

lang=us question

Hi Folks,

I have been using this howto, actually probably the same howto posted on the wiki. I seem to have run into a problem inbetween versions 3.7 and 3.8.2 and haven't been able to get past it so far. After having created the remaster image, booting with knoppix 2 lang=us, copying etc/X11/XF86Config-4 to .../remaster/etc/X11. Start the remaster script and chroot, then chmod on /tmp to 777, su to knoppix, and cd (home). Everything is great until the point where I startx, and it comes up in German. Exporting lang=us prior to startx doesn't help.

I've got to be missing something dumb, could some kind soul please point it out?

TIA,

If I understood your question right, you don't have right locale settings in your remaster partition when starting X. Just copy /etc/sysconfig/i18n from you Knoppix CD to the same location in your remaster partition and check time zone (tzconfig).

Thanks much for the quick reply.

There was no /etc/sysconfig/i18n in the remaster, I copied it from the expanded cd. Now gdk complains local not supported by C library, kde is not supported. It looks like there may be some more files that need to be copied or something? I'll go through the howto after work, maybe I missed something since the change to 3.8.2...

Thanks,

Hey, Thanks for the great scripts! They make it much easier. I used the script and all I want to do is add a directory to / called touchscreen. I chrooted into the remaster directory (using the GUI) and added the directory and put a README file in it just as a test. I ran the knoppix.mksortlist and the new directory was listed as `/touchscreen/README 90`. I created the compressed fs and then the ISO and burned the CD. When I boot the CD the directory is at /KNOPPIX/touchscreen not /touchscreen. Why is that happening and how can I get it to be in /touchscreen.

Thanks

How to keep /home/myuser ?

I am successfully using the script (1000 thanks to UnderScore) and built my own remaster.
I created another user which is also successfully available then in the remastered version, but unfortunatly the home-folder is not there anymore.
Therefore I receive an error-message when logging in with this user, saying that the home-folder cannot be found.
I guess the /home/knoppix directory gets created on-the fly dynamically during boot up.
Do I have to do the same for myuser?
if yes, how?

thank you in advance!

Yes the home directories get created in the linuxrc file located in the minirt24.gz or minirt26.gz depending on which kernel you are running. Chances are that you are running the minirt24. You have to copy the file somewhere, unzip it and them mount it as a loop file (mount -o loop minirt24 /mnt/somwhere... or something like that). Then edit the file to create the directoy and do the reverse. The file is in the Knoppix.master/boot/isolinux directory of the remaster.

Okay, my solution was to add some lines in /etc/init.d/knoppix-autoconfig (lines 1223-1229 in Knoppix 3.8.1) after last "fi":

Code:

# Setting right permissions and owners to /tmp/.ICE-unix and /tmp/.X11-unix mkdir -p /tmp/.ICE-unix 2>/dev/null chown -R root:root /tmp/.ICE-unix 2>/dev/null chmod 1777 /tmp/.ICE-unix 2>/dev/null mkdir -p /tmp/.X11-unix 2>/dev/null chown -R root:root /tmp/.X11-unix 2>/dev/null chmod 1777 /tmp/.X11-unix 2>/dev/null

This corrects that error message and KDE startx a little bit faster. Hope that this would be included in original Knoppix CD too.
