kdump-dep-generator is a systemd generator, used to write out kdump service dependencies. Currently it's only useful for ssh dump case. And in ssh dump case, it writes out a dependency which kdump.service "Wants" network-online.target: # ls -l /run/systemd/generator/kdump.service.wants/ [..] network-online.target -> /usr/lib/systemd/system/network-online.target So that kdump.service will pull in network-online.target and delayed start until network-online.target is reached. In the future, we could use generator to write out kdump.service dynamically and get rid of the static defined kdump.service at all. v1->v2: Vivek: not using hardcoded run time generator path, use what systemd pass in.
