*) FIRSTBOOT:
- calculate manually "size=max" of MAIN partition (workaround for know bug in libparted ``max_size`` class)
- add debug: write LOG to /mnt/log_firstboot.txt
- ditch "/boot/resize" file method
*)MAIN
- add debug: write LOGS to /mnt/log.txt
- cleanup & use tabs for indendent
- use ${HOME} variable often
*) GENIMAGE
- rm "resize" file (no use)
