found the problem. as i use my crunchbang installation a hd music server and run this server in AP (access point) mode using also a bridge to eth0 sometimes the wifi doesn't work.then the boot process gets into trouble . so changed how the mpd server gets stared during boot process. The rebooted into recovery mode and chnaged root passwd and then restarted. now everything works excellent. produced now several dedicated distros. this is so cool.
thank you very much,
Installed crunchmaster_1.2-wheezy on my Waldorf driven machine. Creating a distro .iso worked smoothly and without any problems. Used then the USB stick mode to create a bootable flash drive. Tried then to install from stick. Selected live version from the grub menu which resulted in a booting process that stopped at the startup of x-windows. Repeated the process of creating a distro three times ending every time with the same result.
Obviously a promising tool. Curious what the experiences of other users might be.
