ops I corrected in the text ... I transferred the files in floppy where the partition was mounted not in opt. Sorry for that. I just copied from previous guide. And /opt/ was not touched. I tried to restart the device and everything is fine. However I would like to understand if the command has to be Code: cd /debian /home/user/img-install/ tar cf - . | (cd /floppy/; tar xvf -) or if Code: tar cf - . | (cd /floppy/; tar xvf -) is enough. Thank you very much and sorry for the mistake!
cd /debian /home/user/img-install/ tar cf - . | (cd /floppy/; tar xvf -)
tar cf - . | (cd /floppy/; tar xvf -)
