No, this is not true. If you just boot like a regular operating system, you will trash the crashed kernel making the dump useless.

- loeg 3y agoA crash dumper does not have to be implemented with a reboot; this is just something Linux chooses to do. I have actually worked on kernel code that performs crash dumps to disk and over the network, if you find that kind of expertise relevant.
- worthless-trash 3y agoI really do. I believe kexec/kdump does execute in place and does not go through a full reboot, am I wrong ?
