I think I solved the problems. diskvar was set to $LOGDIR/disk_var.sh during first installation.
FAIBASE/20-save_diskvar copied it to /etc/fai which was the wrong path. FAIBASE/20-save_diskvar is now removed. Now disk_var.sh is copied to /var/log/fai/disk_var.sh, but that is done by task_savelog. During first installation $diskvar is defined, so menu.lst/postinst can use it. If not (during softupdate) the postinst checks if /var/log/fai/disk_var.sh is available and then reads its content. -- regards Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
