+# Dracut-BAS
+
+* Builded on `Ubuntu 20.04 LTS`
+* Used kernel `vmlinuz-5.4.0-42-generic`
+* Dracut Version `050`\
+https://github.com/dracutdevs/dracut
+
+
+Dracut build command
+```bash
+./dracut.sh --no-hostonly --force --local --modules "dracut-systemd systemd-initrd systemd busybox terminfo base bash kernel-modules slx-network shutdown bas-registration-hooks bas-python" initramfs-bas
+```
+
+---
+
+#### Default Dracut modules
+* systemd-initrd
+* systemd
+* terminfo
+* base
+* bash
+* kernel-modules
+* kernel-network-modules (dependency from slx-network)
+* shutdown
+
+---
+
+### SLX-Modules
+Needs to be linked in `dracut/modules.d/` e.g. `90<modulename>`\
+The smaller numbers overrides the bigger ones
+
+#### slx-network
+* unchanged
+
+#### busybox
+* Updated busybox to version `v1.32.0`\
+https://git.busybox.net/busybox/\
+`v1.33.0.git` was working as well
+* link to `00busybox` to override dracut's default busybox
+
+---
+
+### BAS-Modules
+Needs to be linked in `dracut/modules.d/` e.g. `90<modulename>`
+
+#### bas-registration-hooks
+Script for execution the registration hooks\
+Loops and pulls all bash scripts from the BAS until all scripts are finished or the next hook is an ipxe script
+* curl
+* dmidecode
+
+
+#### bas-python
+Better to be linked as `95bas-python`, so that `/opt`, `/usr/lib` and `/usr/local/lib/` already exists\
+Python script that collects hardware information and sends it to different backends (BAS, openslx, ...)
+* Python 3.8
+* Pip 3
+* dmiparser
