Hi,
Let me ask some question:
1) What is the relationship between u-boot, syslinux/extlinux, grub in
installation process of F21 on ARM boxes? (I see elements of all this
environments on the installation image.)
2) Does the u-boot bootloader recognizes full set of extlinux.conf
options? 3) How to build extlinux.conf & ks.cfg to perform fully
automatic installation on Cubieboard2?
Background:
My goal is to configure some Cubieboard2 (Allwinner A20 SoC) boxes to
perform fully automatic installation from PXE server (FOG).
I've done my best to get familiar with contents of:
1) Fedora ARM Installation Procedure

2) u-boot & syslinux change in F21
<

and now .... I have a mess in my head. :-)
I have divided the "project" into few stages.
At the current stage, I try to build a local automatic installation.
(Local only, ie. from miniSD, without potential network
difficulties.) So, I try to construct extlinux.conf/grub.conf and
anaconda kickstart file that will be able to perform fully automatic
installation.
Here is my extlinux.conf file:
ui menu.c32
menu autoboot Welcome to Fedora-Minimal-armhfp-21-5. Automatic boot
in # second{,s}. Press a key for options.
menu title Fedora-Minimal-armhfp-21-5 Boot Options.
menu hidden
timeout 20
totaltimeout 600
label Fedora-Minimal-armhfp-21-5 (3.17.4-301.fc21.armv7hl)
kernel /vmlinuz-3.17.4-301.fc21.armv7hl
append ro root=UUID=e098e36f-f409-44cb-9d8e-9d5c0e2ed9c9
fdtdir /dtb-3.17.4-301.fc21.armv7hl/
initrd /initramfs-3.17.4-301.fc21.armv7hl.img
inst.ks=hd:sdb1:/ks.cfg
label Just to show the extlinux.conf is read
kernel /vmlinuz-3.17.4-301.fc21.armv7hl
append ro root=UUID=e098e36f-f409-44cb-9d8e-9d5c0e2ed9c9
fdtdir /dtb-3.17.4-301.fc21.armv7hl/
initrd /initramfs-3.17.4-301.fc21.armv7hl.img
First, I see that extlinux.conf file is (at least partially)
processed, as the additional label is reflected in options proposed
during installation process. But it seems that the option
inst.ks=hd:sdb1:/ks.cfg is ignored.
you have to put "inst.ks=hd:sdb1:/ks.cfg" on the append line. append is
the boot arguments passed on the kernel.
