This page describes how to debug Dracut. For general information on how to file a bug, should you need to do so, please see Bugs and feature requests.
Identifying your problem area
- Remove rhgb and quiet from the kernel command line
- Add rdshell to the kernel command line. This will present a shell should dracut be unable to locate your root device
- Add rdshell rdinitdebug to the kernel command line so that dracut shell commands are printed as they are executed
- With dracut >= 002-11 [1], you can inspect the rdinitdebug output with:
# less /init.log
# dmesg | less
