Hey guys,

i'm trying to build ISOs using the alpine-iso git-repo Makefile, sadly =
it does not work at all. My first idea was to create .img files to be =
able to boot using memdisk, but apparently that does not work as well.

=3D=3D> Generating alpine-rescue-131027-x86_64.img


I'm not sure about those WARNING, but anyway, after trying to boot this =
img (i also tried the ISO), i get this:

SYSLINUX 5.02 CHS 5.02-pre3 Copyright (C) 1994-2013 H. Peter Anvin et al
boot:
[    0.000000] tsc: Fast TSC calibration failed
Alpine Init 2.5.0-r0
/sbin/init not found in new root. Launching emergency recovery shell
Type exit to continue to boot.
sh: can't access tty; job control turned off
/ #

I also tried booting it using PXE and memdisk which resulted in this =
here:

SYSLINUX 5.02 CHS 5.02-pre3 Copyright (C) 1994-2013 H. Peter Anvin et al
boot:
[    0.000000] tsc: Fast TSC calibration failed
Alpine Init 2.5.0-r0
Mounting boot media failed.
initramfs emergency recovery shell launched. Type 'exit' to continue =
boot
sh: can't access tty; job control turned off
/ #


I already compared the generated img/iso files against the downloaded =
versions, which only seem to differ in the squashfs image size.
syslinux.cfg on the downloaded .iso and the generated one are the same.

Simplest way to reproduce i guess is to try the wiki tutorial =
(http://wiki.alpinelinux.org/wiki/How_to_make_a_custom_ISO_image) =
yourself and test the resulting iso/img with Qemu or VirtualBox.
