multiple initrd/imgfetch in UEFI mode - simonb - 2015-10-09 12:39

Hi,

I'm trying to upload multiple files from my iPXE script to get them during initrd.

It works fine in legacy mode, but I not in UEFI mode.

Code:

#!ipxe

  kernel http://my.web.server/boot/vmlinuz initrd=initrd.img

  initrd http://my.web.server/boot/initrd.img

  initrd http://my.web.server/boot/test.txt /tmp/test.txt

  boot

The file test.txt is correctly loaded (I have done an imgstat after the load) but can not be found under /tmp (neither anywhere) during the initrd phase. It works fine in legacy mode ...

Any advices ?

Note: It took me time to find that the kernel option initrd=<file> is compulsory in UEFI mode (not in legacy)

Thanks,

Simon.

Not yet supported under UEFI, sorry. You can provide multiple initramfs CPIO archives via (from memory) multiple initrd= arguments on the kernel command line, but there's no capability to have iPXE automatically construct the CPIO headers for you (as is done under BIOS).

Thanks for your reply. It does work indeed with :

Code:

#!ipxe

  kernel http://my.web.server/boot/vmlinuz initrd=initrd.img initrd=test.cpio

  initrd http://my.web.server/boot/initrd.img

  initrd http://my.web.server/boot/test.cpio

  boot

with test.cpio created as :

Code:

find tmp

 tmp

 tmp/test.txt

Code:

find tmp |cpio --quiet --dereference -o -H newc > test.cpio

Thanks a lot.

Bertrand.
