Hi,
I'm trying to create a Makefile that would automate remastering Knoppix distribution.
As a part of the process I am mounting using linux cloop device a compressed filesystem and copy the content out of it to separate dir. However during that process I need to preserve hard links and it seems it is not working.
I've tried using:
- cp -a --preserve=all
- rsync -a -H
- tar | tar version
All of them are making original hard-linked files a separate files.
The lines in the code are:
#sudo nice tar -C $(NAME).cloop -cf - . | sudo nice tar -C $(NAME).tree -xvpf -
sudo cp -av --preserve=all $(NAME).cloop $(NAME).tree
#sudo rsync -x -a -H --progress --delete $(NAME).cloop/ $(NAME).tree
Can you please advise what can be wrong?
Below is the full content of the Makefile

The command:
make changes
will work for a longer moment and produce changes file which is a diff of mounted cloop device and copyied tree content.
