+==== Debugging dracut on shutdown
|
|
+
|
|
+To debug the shutdown sequence on systemd systems, you can _rd.break_
|
|
+on _pre-shutdown_ or _shutdown_.
|
|
+
|
|
+To do this from an already booted system:
|
|
+----
|
|
+# mkdir -p /run/initramfs/etc/cmdline.d
|
|
+# echo "rd.break=pre-shutdown" > /run/initramfs/etc/cmdline.d/debug.conf
|
|
+# touch /run/initramfs/.need_shutdown
|
|
+----
|
|
+
|
|
+This will give you a dracut shell after the system pivot'ed back in the initramfs.
