abcd

Simple init system in bash for critical operations that must run before the actual init system.

Usage

1. Clone the repository

2. Rename the abcd file to /usr/sbin/init or wherever your init file is located and make it executable.

3. Create a file /usr/share/abcd/abcd.nextInit.conf with the following content:

   /lib/systemd/systemd
   

   in case of systemd, or update the path to your init system of choice.

4. Create the directory /usr/share/abcd/abc.d and put your hooks in there. They will be executed in alphabetical order, so it is better to prefix them with numbers, e.g. 000-prepare.sh, 100-mount.sh, 200-network.sh, etc. Remember to set them as executable and to include the shebang line, for example:

   #!/bin/bash
   echo "Mounting filesystems"

5. Reboot

Debug

All the messages are logged to dmesg, so you can check them with dmesg | grep abcd from a chroot environment.
