Subject: [alpine-user] Multiple initramfs appears not to work

Hi folks,

I want to pass multiple initramfs file to Alpine on boot.

The architecture document says it supports such behaviour:
https://wiki.alpinelinux.org/wiki/Architecture
"The kernel will decompress the stream of compressed cpio archives =
passed to it by the 'append' bootloader option to the root of 'rootfs', =
a tmpfs automatically mounted at '/' by the kernel at boot."


As far as I can tell, Alpine appears to ignore all except the first =
initramfs.

I=E2=80=99ve searching the web extensively to find any syslinux.cfg =
example that does this for Alpine Linux but can find none, so I=E2=80=99m =
wondering if it has ever been tested or known to work.

I=E2=80=99ve tried a variety of different ways of specifying in =
syslinux.cfg but none of them seem to work. Here is an example of one =
such config.

SERIAL 0 115200
TIMEOUT 20
PROMPT 1
DEFAULT virthardened

LABEL virthardened
MENU LABEL Linux virthardened
KERNEL /boot/vmlinuz-virthardened
INITRD /boot/initramfs-virthardened,/boot/rootfs_overlay_initramfs.gz
DEVICETREEDIR /boot/dtbs
APPEND modules=3Dloop,squashfs,sd-mod,usb-storage quiet console=3Dtty0 =
console=3DttyS0,115200

Is anyone able to help me get Alpine to load more than one initramfs?

thanks

Andrew
