[alpine-devel] Problems building ISO/img (especially for pxe boot)

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.

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.
