## Why Arch? ##
|
|
|
|
|
|
Because it's a largely easy-to-use, well-documented (https://wiki.archlinux.org/) distro. It's no-frills and incredibly
|
|
|
|
|
|
flexible/customizable, and can be made rather slim. It's also very friendly to run as a chroot inside any other distro.
|
|
|
|
|
|
|
|
|
|
|
|
All commands below should be issued in the root working directory of this git repository. (For me, this is
|
|
|
|
|
|
/opt/dev/work/BDisk but this may be entirely different for you, depending on where you cloned the repository to.)
|
|
|
|
|
|
|

|
|
|
|
!!!!!! WARNING !!!!!!!
|
|
|
|
|
|
I do NOT recommend running this on a machine that is using wireless, as it will download a LOT of data.
|
|
|
|
|
|
If you ignore this warning, be prepared to explain to anyone you share your wifi with why Facebook takes 20 seconds to load,
|
|
|
|
|
|
because they WILL ask.
|
|
|
|
|
|
|
|
|
|
|
|
It should be fine over ethernet, since hardware switches are much faster and efficient than a single duplex wireless radio.
|
|
|
|
|
|
|
|
|
|
|
|
Future versions, once this project has a dumping ground, will fetch highly compressed snapshotted chroot filesystems instead
|
|
|
|
|
|
of dynamically building the entire install chroots (both x86_64 and i686) instead (with the option of building fresh locally,
|
|
|
|
|
|
disabled by default).
|
|
|
|
|
|
Till then, sorry for the inconvenience.
|

## Prerequisites ##
|
|
|
|
|
|
-At least ~20Gb disk space free (remember, you need room for not only four chroots (one developing and one staging for i686/x86_64),
|
|
|
|
|
|
but also disk space for working, the finished ISO(s), etc.)
|
|
|
|
|
|
|
|
|
|
|
|
-The following packages installed on the build host:
|
|
|
|
|
|
(NOTE: future versions will have dependencies checked automatically and installed if necessary,
|
|
|
|
|
|
depending on distro your host build machine is. the OS detection and package installation component of that isn't
|
|
|
|
|
|
done yet though. 2014.10.31)
|
2014-12-20 12:09:15 -05:00
|
|
|
|
(NOTE2: Make sure all the packages you specify are valid package names. A mistyped package name will cause the chroot creation to
|
|
|
|
|
|
break and everything else will break as a result.)

## (Re)Building ##
|
|
|
|
|
|
$ sudo bin/build.sh
|
|
|
|
|
|
|
|
|
|
|
|
Yeah. It's that easy. The finished product is in iso/.
|
|
|
|
|
|
|
|
|
|
|
|
Build output should look something like this:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
[root@dawid BDisk]# time nice -n "-19" bin/build.sh
|
|
|
|
|
|
You have not configured a build.conf OR you are not running from the project's root directory (the git repository's working directory).
|
|
|
|
|
|
If you are indeed in the correct directory, you may copy the sample at extra/build.conf.sample,
|
|
|
|
|
|
edit it for appropriate values, and copy to <PROJECT ROOT>/build.conf
|
|
|
|
|
|
For now, though, I am copying over the default.
