Re: 2010.07-1 archboot "2k10-R5" ISO hybrid image released

Tpowa:

Interesting project you have going.  I note it is isolinux-related and that is of interest to me.
I have a OS derivative from Calimero called CTKarchlive which employs isolinux and has the capability of installing cp2ram.

I am wondering if the common use of isolinux would permit both your program and the CTK program to be installed to the same drive.  The CTK version I have is 64 bit and registers as UDF, since it is intended for CD/DVD.  I use it in a sata2CF adapter and it performs very well.

I suspect that cp2ram should be amenable with your syslinux bootloader and that installed in the same flash drive could be selected at boot prompt for either system.

I note from googling that extlinux is applied to a mounted filesystem which is somewhat different than usual practice.

EDIT:  Use of CF card in this manner (cp2ram) ensures long life for the flash device.  It also provides the fastest response time in the system for most operations.

Your comments are invited.

Re: 2010.07-1 archboot "2k10-R5" ISO hybrid image released

I installed it into an existing btrfs and it works awesome smile

it just annoying that he installed everything into ext2_saved instead of / so i had to move the whole system out of ext2_saved to /

also i had to adjust the /etc/fstab to remove the subvolume option from mount

i also had to remove the subvolume option from syslinux but i do it every boot by hand cause i have no clue where the syslinux.cfg file is gone...

found it /boot/extlinux.cfg

Do you select install packages too? Does pacman output anything?

This weekend I will download the image again and report back.

Re: 2010.07-1 archboot "2k10-R5" ISO hybrid image released

ok btrfs subvolume issue is solved, it was a missing check in extlinux.
For all here, extlinux doesn't support pure subvolume btrfs!
You need a separate /boot partition!

the iso is available only in some selected mirrors. It is not there in  http://mir.archlinux.fr/ mirror (here it is better choice to get the downloads faster) Now downloading from kernel.org

Syslinux should abort immediatly, you have no vfat partition selected to install on.

- I again confirm the behaviour of dropping to installation environment
   here is the video taken during installation
- now config files are ok.
- in the earlier release also i mentioned about the modules array

   will not the MOD_AUTOLOAD="yes" alone work?
remaining everything went smooth.
thanks.

- The torrent should be seeded by webseeds too, then it should be imho faster to download.
- The dropping into setup on first login is normal behaviour, that you can change keymap.
  When you leave setup no more setup session will startup automatically.
- The Modules array is created that way, to ensure network and soundcard consistency on reboot.
  If you have 2 cards they might change during reboot, due to udev loading modules in no order.

So all is fine, ftp installation mode got some important correction in git tree to have a smooth installation on next iso.

Re: 2010.07-1 archboot "2k10-R5" ISO hybrid image released

I tried to create a UEFI based Archboot cd but I need to use Xorriso http://scdbackup.sourceforge.net/xorriso_eng.html  (community/libisoburn package). It includes a -efi-boot option to specify a efi el-torito boot image. Can you provide a equivalent xorriso command for using in archboot-allinone.sh instead of mkisofs?

Another Q : Which file should I use to create a x86_64 only Archboot iso (not dual arch) or how should I modify archboot-allinone.sh to remove i686 related stuff and LTS kernels related stuff? Thank you.

archboot-allinone.sh      archboot-svn.sh          archboot-testing-package.sh  copy-mountpoint.sh
archboot-find-changes.sh  archboot-tarball-helper.sh  archboot-usbimage-helper.sh

Re: 2010.07-1 archboot "2k10-R5" ISO hybrid image released

I noticed that while choosing GPT, you recommend a 10MB bios_grub (BIOS Boot) partition. Bios Boot partition is used for embedding the generated core.img as there is no 63 sector gap after the protective mbr to embed it. It needs not be bigger than 1MB. A bios_grub partition is needed only for BIOS+GPT, not for UEFI+MBR or UEFI+GPT combination.

Also in case of autoprepare HDD, what partition alignment is being used. Considering the release of 4096-byte sector HDDs (Advanced format drives), I think a 1MB alignment will prevent any future performance issues and in any case no CHS issues exist, atleast in case of GPT.

Re: 2010.07-1 archboot "2k10-R5" ISO hybrid image released

Tell me how, i didn't find a way to do it. sfdisk can only do 10mb partitions.
In autoprepare mode it depends on what you choose, gpt or bios.

Re: 2010.07-1 archboot "2k10-R5" ISO hybrid image released

Why is sfdisk involved for GPT? bios_grub is used only in case of grub2+BIOS+GPT combination not for any other use-case. This part will not be used for grub2+BIOS+MBR combination. No such partition type code currently exists for MBR where grub2 embeds its core.img (although this may change in future).

If you meant sgdisk, both gdisk and sgdisk by default do 1 MB alignment unless you explicitly override it. util-linux-ng's cfdisk, sfdisk or even fdisk should not come up when GPT is chosen. Only gdisk should come up. None of the main fdisk utils support GPT.

gdisk by default uses 2048 sector alignment for 512-byte sector drives which translates to 1 MB alignment.

http://www.ibm.com/developerworks/linux … tor-disks/ - witten by gdisk author Rod Smith.
http://rodsbooks.com/gdisk/booting.html - in the case of GRUB2, the BIOS Boot Partition can be quite small—perhaps as small as 32KiB, although I recommend making it 100-200 KiB, if possible

I recommend 1 MB.

Sorry for gpt parted is used not sfdisk.
parted -s $DEVICE mkpart 1 ext2 0 $GUID_PART_SIZE >$LOG
The GUID_PART_SIZE i use is 10, this means a 1 would be enough correct?
