Confirming - /usr/lib/genfstab.awk overwritten by CSSU'ish version was case of my problems, and I suppose, that it's same for everyone else, that get into reboot-loop after updating system-services (via latest thumb, or manually). It should affect only people using different filesystem for /home + opt Fix: Edit line 20 in genfstab.awk, changing hardcoded "ext3" to filesystem of Your choice. In case of less popular filesystems, You may want to edit mount options, too - everything must match Your filesystem requiments. Thanks a lot to freemangordon for patiently helping on finding issue. /Estel
