46.2.3.4. Changing the Default Action
By default, when
kdump fails to create a core dump, the root file system is mounted and /sbin/init is run. To change this behavior, open the /etc/kdump.conf configuration file as root, remove the hash sign (“#”) from the beginning of the #default shell line, and replace the value with a desired action as described in Table 46.2, “Supported actions”. For example:
default halt
| Option | Action |
|---|---|
reboot | Reboot the system, losing the core in the process. |
halt | After failing to capture a core, halt the system. |
shell | Run the msh session from within the initramfs, allowing a user to record the core manually. |
