APK Build Chroot tool

There are various build chains surrounding Alpine. Most solutions use containerization, QEMU, and other technologies; meanwhile I just wanted a simple way to build packages and install development utilities without shitting up my production system. abchr is an attempt to create a simple solution to my simple problem. It isn't very flexible, requires root access for chroot, and won't allow you to (easily) build for multiarch, but it works.

Installation

1. Create a directory and three subdirectories named bin, alpine, and aports. Your tree should look like this:

   + abchr
     + bin
     + alpine
     + aports
   

2. Clone the repo to the bin directory.
3. Run abchr-newchroot $(id -u) to populate the alpine directory with a new installation of Alpine Linux. This processes downloads the latest apk-tools-static into the chroot and installs the basic packages necessary for a build environment. It also creates a user in the chroot with its UID set to the first argument of the script. Having this be your own UID is optimal as it lets you manupulate the chroot files easily.
4. To ensure everything worked, run abchr abuild -h. You should see the help text for abuild, which should be installed in the chroot.

Usage

The abchr command simply sets up the chroot and starts whatever program is specified in the arguments as-is. There are some exceptions, meant for ease-of-use; run abchr -h to see what the script is capable of.
