Good morning from Singapore,


Can I build Arch Linux from Scratch like Linux from Scratch?


Please advise.


Thank you.

Hi,

you are probably the only one to know, if you could or could not achieve
the same regarding your needs by either using LFS or Arch Linux.

At the right side of the homepage is the link to the Wiki
(https://wiki.archlinux.org/
maybe start with the Arch Wiki's FAQ
https://wiki.archlinux.org/index.php/Frequently_asked_questions , the
FAQ provide a lot of links. For example a link to
https://wiki.archlinux.org/index.php/Arch_compared_to_other_distributions
that links to https://wiki.archlinux.org/index.php/Arch_Build_System)
and the right side of the homepage also contains a link to the
Installation Guide(https://wiki.archlinux.org/index.php/Installation_guide)
wich also links to the FAQ.

Regards,
Ralf

Good morning from Singapore,
Can I build Arch Linux from Scratch like Linux from Scratch?
It's certainly possible to build all of ArchLinux's packages from source
using the ABS. My approach would be to start on any Linux distribution by
building Pacman, which will provide the makepkg script to allow you to
start building Arch packages from source using PKGBUILD files. You'd want
to start with the packages in the "base" group, followed by base-devel. You
should be able to use Pacman to install each package file into a chroot, at
which point your Arch system will be bootstrapped.

But that's a lot of work. It's an interesting project, but I'm not sure
there's much to be gained, practically, by building Arch like this as
opposed to installing the pre-built packages.

There are a few dependency cycles that may have to be build in stages
with bootstrap packages. First build package "one" without dependency on
"two", then build "two" with dependency on "one", then rebuild "one",
this time with dependency on "two". Maybe rebuild "two" as well. These
bootstrap PKGBUILDs do not exist in the archlinux sources, so you have
to create them on your own.
