Hi everyone. I want to remove all the graphics from the .iso. I found the docs for editing it but what do I need to remove? Also, how do I add an extension?
-
You won't gain more than 2-3mb by removing the gui, but if you still wish to do so, the biggest parts are Xvesa, jwm, X libs, and libfltk. Then there are the fltk guis, but they are only a couple of kb each.
How to add an extension to the iso:
just create a new directory "tce" right beside the directory "boot", so it's at the top level of the to-be-iso, and put extensions into that tce directory.

thanks curaga. size does not matter. i'm going to add 3.5GB to it when the GUI is removed.

i used to edit bootable iso's with isomaster (not available for tc, but as i'm about to mention not as useful tc users either) but sadly, tc's iso is not compatible with isomaster. it won't let you save the new .iso file.
there are some very sophisticated, powerful (and complicated) remaster scripts for remastering tc, and there are some "easy" (well, close enough) wiki instructions for taking tc apart, and i'm comfortable using mkisofs (included with cdrtools.tce)
...but what i'd really like to know is just where to get a boot image for tc (not the kernel bzImage) so i could just mkisofs + whatever options i normally use + the option for bootimage: this-is-the-part-i'm-asking-about.
i could look up the letter for the option in mkisofs, that's no problem. it's where to get the boot image (isolinux i imagine) that i don't know. then remastering the iso (nevermind editing tinycore.gz...) would be relatively easy- only since isomaster (the friendliest way possible to add files to a bootable iso) is not an option, and multisession is not always the ideal way to add files to a cd (let alone a cd image.)
-
A boot image? Most linux distros don't use that old floppy emulation mode. If you copy all the files from a TC iso, the isolinux files will be there, and the mkisofs instruction on the wiki will create a bootable iso.
-
I just do my remater manually:
mkdir tmp;cd tmp
gzip -cd ../tinycore.gz | sudo cpio -id
-edit files-
find . | cpio --create --format='newc' | gzip -c ../newinitrd.gz
cd ..Then newinitd.gz replaces tinycore.gz in the new ISO.
-
the mkisofs instruction on the wiki will create a bootable iso.
thanks, i'll try that.

This list is what I removed to bring down tinycore.gz from 8.3MB to 3.9MB. But only do this if you know what you are doing and what has to be put back in the base for certain extensions to function. In other words, if you strip your tinycore.gz don't ask why certain extensions or base items no longer function. More could be pruned or left in but this was my starting point, just that a starting point and not a guaranteed working system.

If size doesn't matter, might I just suggest that you disable the starting of the X system. I think you could accomplish this simply by using the "text" boot option, or by editing /home/tc/.profile
-
I just got referred to this thread as it was exactly what I was looking for.
I copied Jason W's pastebin list into a file I called 'gui_files' and then ran this script I created:
for FILE in `cat gui_files`
do
echo Removing $FILE
rm -f $FILE
done
NB. the script and 'gui_files' need to be run in the extract directory and please, please make sure the list in 'gui_files' has no leading forward slashes, eg. make sure you use 'etc/font/...' and NOT '/etc/font/...'.
The script comes with absolutely no warranty so make sure you understand what it will do before you run it.
The TCL community in action. ;D
-
Do you have the list available? the pastebin seems to have been inactivated.
-
I will look and see if I still have it tomorrow.
-
i know that for pasting things like massive dmesg lists, pastebin might be better and more polite, but for something that's likely to be used in the future, like this list, perhaps it would be better to actually post it on the forum? if not as text then perhaps as a tar.gz.
not as a tce. as a tce people will try it, and wonder what they just did.

What about putting it in the wiki under the remastering section?
-
Xvesa, jwm, X libs, and libfltk
Hello,
i would like to remove whole GUI to strip away size below 10mb. Now i have checked remaster wiki section and forum and all i found was post above to remove Xvesa, xlibs and fltk files. I did this and repacked back. Now when i boot it i get few errors during boot. Those are;
SQUASHFS error: ... => couldnt write it down as it is during boot
xauth: error while loading shared libraries: lixXau.so.6: cannot open shared object file: No such file or directory
/home/tc/.xsession: line 1: Xvesa: not found
Can somebody write how to remove those errors/warnings?
-
Maybe you missed the announcment. Just boot tinycore 2.0rc3 with the microcore boot option.
Result no X no GUI only CLI.
-
Well i dont want to boot into console and still have files from GUI on the filesystem, because i am limited to the disk space i removed them and thats why i ask how to remove those warnings/errors.
-
They are more easily removable in rc3; but with your remaster, try adding the "text" bootcode so TC doesn't try to start the removed X.
