*** Alternative boot methods (configs/releng)
|
||||
|
||||
ISO images names consist of: archlinux-<YYYY>.<MM>.<DD>-x86_64.iso
|
||||
|
||||
Where:
|
||||
<YYYY> Year
|
||||
<MM> Month
|
||||
<DD> Day
|
||||
|
||||
|
||||
** ISO in loopback mode.
|
||||
|
||||
Note: Described method is for using with GRUB2.
|
||||
GRUB2 is installed on target media and archlinux-<YYYY>.<MM>.<DD>-x86_64.iso
|
||||
is at path <TARGET-PATH> on disk <D> and partition <P>,
|
||||
where filesystem is labeled as <TARGET-FS-LABEL>.
|
||||
|
||||
menuentry "Arch Linux (x86_64)" {
|
||||
set isofile="/<TARGET-PATH>/archlinux-<YYYY>.<MM>.<DD>-x86_64.iso"
|
||||
loopback loop (hd<D>,<P>)$isofile
|
||||
linux (loop)/arch/boot/x86_64/vmlinuz img_label=<TARGET-FS-LABEL> img_loop=$isofile
|
||||
initrd (loop)/arch/boot/x86_64/archiso.img
|
||||
}
|
||||
|
||||
|
||||
** ISO in memdisk mode.
|
||||
|
||||
Note: Described method is for using with SYSLINUX. Anyway MEMDISK from SYSLINUX can work
|
||||
with other bootloaders.
|
||||
SYSLINUX is installed on target media and archlinux-<YYYY>.<MM>.<DD>-x86_64.iso
|
||||
is at path <TARGET-PATH>.
|
||||
|
||||
|
||||
LABEL arch_x64
|
||||
LINUX memdisk
|
||||
INITRD /<TARGET-PATH>/archlinux-<YYYY>.<MM>.<DD>-x86_64.iso
|
||||
APPEND iso
|
||||
|
||||
|
||||
** Network booting (PXE).
|
||||
|
||||
All ISOs are ready to act as PXE server, some manual steps are needed
|
||||
to setup the desired PXE boot mode.
|
||||
Alternatively it is possible to use an existing PXE server following the same logic.
|
||||
Note: Setup network first, adjust IP adresses, and respect all slashes "/".
|
||||
|
||||
First stage is for loading kernel and initramfs via PXE, two methods described here:
|
||||
|
||||
* DHCP + TFTP
|
||||
|
||||
Note: All NIC firmwares should support this.
|
||||
|
||||
# dnsmasq --port=0 \
|
||||
--enable-tftp \
|
||||
--tftp-root=/run/archiso/bootmnt \
|
||||
--dhcp-range=192.168.0.2,192.168.0.254,86400 \
|
||||
--dhcp-boot=/arch/boot/syslinux/lpxelinux.0 \
|
||||
--dhcp-option-force=209,boot/syslinux/archiso.cfg \
|
||||
--dhcp-option-force=210,/arch/
|
||||
|
||||
* DHCP + HTTP
|
||||
|
||||
Note: Not all NIC firmware supports HTTP and DNS (if domain name is used).
|
||||
At least this works with iPXE and gPXE.
|
||||
|
||||
# dnsmasq --port=0 \
|
||||
--dhcp-range=192.168.0.2,192.168.0.254,86400 \
|
||||
--dhcp-boot=http://192.168.0.7/arch/boot/syslinux/lpxelinux.0 \
|
||||
--dhcp-option-force=209,boot/syslinux/archiso.cfg \
|
||||
--dhcp-option-force=210,http://192.168.0.7/arch/
|
||||
|
||||
|
||||
Once the kernel is started from PXE, SquashFS files and other misc files
|
||||
inside "arch" directory must be loaded (second stage). One of the following
|
||||
methods can be used to serve the rest of live-medium.
|
||||
|
||||
* HTTP
|
||||
|
||||
# darkhttpd /run/archiso/bootmnt
|
||||
|
||||
|
||||
* NFS
|
||||
|
||||
# echo "/run/archiso/bootmnt 192.168.0.*(ro,no_subtree_check,no_root_squash)" >> /etc/exports
|
||||
# systemctl start nfs-server.service
|
||||
|
||||
|
||||
* NBD
|
||||
|
||||
Note: Adjust ARCH_201703 as needed.
|
||||
|
||||
# cat << EOF > /tmp/nbd-server.conf
|
||||
[generic]
|
||||
[archiso]
|
||||
readonly = true
|
||||
exportname = /dev/disk/by-label/ARCH_201703
|
||||
EOF
|
||||
# nbd-server -C /tmp/nbd-server.conf
