Re: How to extract the content of the Knoppix 5.3.0 minirt.gz ?

Well I gave it a try... and then another.
Then I backed up my knoppix.img.
Then I did the commands that previously gave me all kinds of
errors... as root.
Which produced only the expected output about removing
leading slash...

gunzip minirt.gz
mkdir init_tmp
cd init_tmp

cpio -imvd --no-absolute-filenames -I ../minirt
yada yada yada... well all I did here was touch ./linuxrc
find . | cpio --quiet -o -H newc | gzip -9 >
../minirt.gz

and the new minirt.gz is about the same size as the
original.
It booted up ok.

What's with the error about a missing selinuxfs on these
minirts?

Well after wondering what the missing 2k bytes or so were...
it would
seem that because ~lib is restored as a link... whatever is
below
can't be restored in the relative tree maybe.
Same with files under ~sbin.

lib/terminfo/l/linux
and sbin/mount.ntfs  as well as sbin/mount.ntfs-3g are
missing after
the restore to the working directory.

There's the 2k.
So that doesn't reall work to well.

Just for completeness sake...
The answer to this riddle is... you must have a chroot setup
to extract it to.
I made a quick and dirty chroot to see and left my steps to
make one here.
