Hi Lukas,
I suggest you create an additional cpio archive (newc format) which > just contains the filesystem.squashfs file (in the appropriate folder) > and nothing else. > > Now you have multiple options: > > 1.

You can do the same as (2) without the compression (which makes > more sense since the squashfs file is already compressed), but then > you might have to add null bytes to initrd.img first so the archive > is properly aligned (see [1]) > > Option 2 sounds like an elegant solution. I tried it but it didn't seem to work, I did this (after building images with live-build in ~/lbinitrd): echo ~/lbinitrd/binary/live/filesystem.squashfs | cpio -o -H newc | gzip -9 > filesystem.cpio.gz cat filesystem.cpio.gz >> initrd.img That should be the same as option 2? At boot I get an error message, "(initramfs) Unable to find a medium containing a live file system". I'm guessing that the contents of the appended cpio archive isn't added to the initramfs. Cheers, Daniel
