Using the F16 pxeboot install images, I see this... dracut: root was live:/squashfs.img, liveroot is now live:/squashfs.img EXT4-fs (dm-0) mounted filesystem with ordered data mode. Opts: (null) Mounted root filesystem /dev/mapper/live-rw dracut: Warning: Signal caught! Dropping to debug shell.
Created attachment 533650 [details] dmesg output with rd_debug dmesg output with rd_debug
ah, this is the "--loglevel=debug" kernel command line parameter, which the kernel blindly assigns to an environment variable called "--loglevel" with the value "debug". The dash shell really does not like it. dash bug 738494 dracut bug 733674 ( seems only partially solved )
