Archboot (العربية)

ما هو Archboot?

• Archboot is a set of scripts to generate bootable media for CD/USB/PXE.
• It is designed for installation or rescue operation.
• It only runs in RAM, without any special filesystems like squashfs, thus it is limited to the RAM which is installed in your system.

Install archboot from the official repositories.

إصدارات Archboot ISO

• Hybrid image files and torrents are provided, which include i686 and/or x86_64 core repository.
• Please read the according Changelog files for RAM limitations.
• Please check md5sum before using it.

Hybrid image file is a standard CD-burnable image and also a raw disk image.

• Can be burned to CD(RW) media using most CD-burning utilities.
• Can be raw-written to a drive using 'dd' or similar utilities. This method is intended for use with USB thumb drives.

'dd if=<imagefile> of=/dev/<yourdevice> bs=1M'

أنماط الإقلاع المدعومة في وسيط تثبيت Archboot

• تدعم إقلع BIOS مع syslinux.
• It supports UEFI booting with gummiboot and EFISTUB,

for booting LTS kernels with efilinux-efi .

(only UEFI USB is supported, UEFI CD booting is not supported!)

• It supports grub's iso loopback support.

variables used (below for example):

iso_loop_dev=UUID=XXXX

iso_loop_path=/blah/archboot.iso

• It supports booting using syslinux's memdisk (only in BIOS mode).

نظام PXE للإقلاع/الإنقاذ

Download 2013.03 „2k13-R1“ needed files from the directory.

• vmlinuz_i686 + initramfs_i686.img (i686)
• vmlinuz_x86_64 + initramfs_x86_64.img(x86_64)
• vmlinuz_i686_lts + initramfs_i686.img (i686 LTS kernel)
• vmlinuz_x86_64_lts + initramfs_x86_64.img (x86_64 LTS kernel)
• For PXE booting add the kernel and initrd to your tftp setup and you will get a running installation/rescue system.
• For Rescue booting add an entry to your bootloader pointing to the kernel and initrd.

• uvesafb

enables uvesafb mode during boot and activates setup routine to use it later on installed system.

you need to specify your supported resolution eg.:

uvesafb=<resolution>-<depth>

uvesafb=1024x768-16

• fbmodule

Loads the fb module you specify durin boot process and activates setup routine to use it later on installed system.

Use it like this fbmodule=<yourmodule>, e.g. fbmodule=cirrusfb

FAQ, القيود والمشكلات المعروفة

• Release specific known issues and workarounds are posted in changelog files.
• Check also the forum threads for posted fixes and workarounds.
• Why screen stays blank or other weird screen issues happen?

Some hardware doesn't like the KMS activation, use radeon.modeset=0 or i915.modeset=0 on boot prompt.

• dmraid might be broken on some boards, support is not perfect here.

The reason is there are so many different hardware components out there. At the moment 1.0.0rc16 is included, with latest fedora patchset.

• grub2 cannot detect correct bios boot order:

It may happen that hd(x,x) entries are not correct, thus first reboot may not work.

Reason: grub cannot detect bios boot order.

Fix: Either change bios boot order or change menu.lst to correct entries after successful boot. This cannot be fixed it is a restriction in grub/grub2!

• Why is parted used in setup routine, instead of cfdisk in msdos partitiontable mode?

parted is the only linux partition program that can handle all type of things the setup routine offers.

cfdisk cannot handle GPT/GUID nor it can allign partitions correct with 1MB spaces for 4k sector disks.

cfdisk is a nice tool but is too limited to be the standard partitioner anymore.

cfdisk is still included but has to be run in an other terminal.

قرص USB للاستعادة

Take care about which device actually is your USB stick. The next command will render all data on /dev/sdX inaccessible.

• First, wipe the bootsector of the USB stick:

dd if=/dev/zero of=/dev/sdX bs=512 count=1

• Then, create a new FAT32 partition on the stick and write a FAT32 filesystem on it (vfat or type b in fdisk terminology):

fdisk /dev/sdX <<EOF
n
p
1

t
b
w
EOF

mkdosfs -F32 /dev/sdX1

• x86_64 architecture
• archboot ISO
• ~ 3GB free space on disk

إنشاء بيئة محول الجذر في archboot

# install archboot
pacman -S archboot
mkdir <x86_64_chroot>
pacman --root "<x86_64_chroot>" -S base --noconfirm --noprogressbar
mkdir <i686_chroot>
linux32 pacman --root "<i686_chroot>" -S base --noconfirm --noprogressbar

• Mount and copy the following files to each chroot:

mount -o bind /dev <chrootpath>/dev
mount -o bind /tmp <chrootpath>/tmp
mount -o bind /sys <chrootpath>/sys
mount -o bind /proc <chrootpath>/proc
cp -a /etc/mtab <chrootpath>/etc/mtab
cp /etc/resolv.conf  <chrootpath>/etc/resolv.conf

• Enter archboot x86_64 chroot:

chroot <chrootpath>

• Enter archboot i686 chroot:

linux32 chroot <chrootpath>

# run in both chroots (needs quite some time ...)

• Finished you get a burnable iso image, a rawwrite usb image and a hybrid image which is both in one.
• Do not forget to unmount for each chroot after leaving:

umount <chrootpath>/dev
umount <chrootpath>/tmp
umount <chrootpath>/sys
umount <chrootpath>/proc
