I don't get it.
If you're just putting the gcc/gnu-utils unc files next to the KNOPPIX file, that can be done with mkmydsl.
If you're remastering KNOPPIX, you have no need for unc because you can install files directly to the base filesystem.

I agree with roberts...there is no apparent reason to convert uci to unc. A uci file is already built to run from a mounted location, without the extra work of linking it into the base system with unionfs. Just about any other package type (deb, rpm, dotpup) will be more appropriate to convert to unc than a uci would be.

Hi mikshaw!

Have you checked the latest Remastering HOWTO (page 62)? The point is that it all ends up INSIDE the KNOPPIX file and it can be done very fast and easy. Furthermore it's intended for use with USB pendrives or as in my case a CF-card. Where you can swap to another KNOPPIX file easily and then just reboot and fire up your remastered version of DSL.

As always have fun,

Apparently the unionfs implementation "supermounts" on the /KNOPPIX cloop, which was previously uneditable. Not that I understand the implementation itself (yet) - but I can see how this can be handy if you are making remaster a lot without scripts.

Unfortunately doing it this way doesn't seem to work in all cases. My first test was with the XFree86.unc. It looks like a uci in the fact its also mounted in /opt, with a user.tar.gz - but I think unionfs kicks in here and the XF86 usr data is accessible through /KNOPPIX. However, user.tar.gz is mydsl-loaded 'normally' and only goes into /ramdisk , but unionfs doesn't touch it (therefore not in /KNOPPIX).

In addition, trying to remove a file from this... such as /usr/X11R6/bin/XFree86 (which would be on /ramdisk) results in a segfault, and consequent things, such as ls /usr/X11R6/bin will results in the program hanging. I assume you can only modified those loaded by unionfs to be modified through that interface.

This is how I understand it so far... feel free to explain, etc.
