Hi, I am playing around with a Gentoo root filesystem on a squash image on a USB stick. I am trying to boot it with dracut dmsquash-live module. It fails with error mount: unknown filesystem type 'DM_snapshot_cow' repeated quite some times. I checked if it is a kernel config problem: DM_SNAPSHOT [=y]. So I guess that is fine. Searching for COW does not five me anything usefull, except for BLK_DEV_COW_COMMON [=n]. But it is not mentioned where in the menuconfig it is mentioned to select. Setting this option directly in .config gets undone when compiling the kernel. kernel-3.10.17-gentoo sys-kernel/dracut-034-r2 USE="device-mapper -debug -net (-selinux)" DRACUT_MODULES="dmsquash-live lvm plymouth -biosdevname -bootchart -btrfs -caps -cifs -crypt -crypt-gpg -crypt-loop -dash -dmraid -gensplash -iscsi -livenet -mdraid -multipath -nbd -nfs -ssh-client -syslog -systemd" Kernel command line: "root=live:UUID=81689ddf-98ab-4314-b420-ce78d505f919 rw init=/usr/lib/systemd/systemd" squashfs.img resides in LiveOS directory on root of USB stick with above UUID.
