Hi again,

I actually solved this for now by hacking /etc/init.d/modloop:


diff --git a/main/openrc/modloop.initd b/main/openrc/modloop.initd
index 87069b487a..5491ca029f 100755
--- a/main/openrc/modloop.initd
+++ b/main/openrc/modloop.initd
@@ -31,7 +31,10 @@ find_modloop() {
  	IFS="$oifs"
  	for line; do
  		img=${line%%:*}
-		verify_modloop "$img" || eerror "Failed to verify signature of $img!"
+		if ! verify_modloop "$img"; then
+			eerror "Failed to verify signature of $img!"
+			continue
+		fi
  		mount "$img" -o loop,ro /.modloop || continue
  		if [ -d /.modloop/modules/$kver ]; then
  			return 0


and by adjusting initfs_cmdline in my custom profile:


initfs_cmdline="$initfs_cmdline apkovl=/media/sr0/alpine.apkovl.tar.gz"



I think "the correct" solution would be to look only in the drive from 
where Linux was booted, but I don't know how initramfs could 
unambiguously tell which drive was the boot drive. My know-how runs out 
early.
