You did not get the point. ;)

I do not want to use external media to boot the system. (You know Murphy...
If the system breaks for whatever reason the media is not nearby.) The iso
file is located on the local disk on a logical volume. Grub can load kernel
and initramfs from there, but the kernel can not access its root file system.

So my request is not about accessing the volumes from inside system (that
works without problems) but about booting the system from lvm.
main(a){char*c=/*    Schoene Gruesse                         */"B?IJj;MEH"
"CX:;",b;for(a/*    Chris           get my mail address:    */=0;b=c[a++];)
putchar(b-1/(/*               gcc -o sig sig.c && ./sig    */b/42*2-3)*42);}
