Add systemd's kdump service command-line regardless if user provides or not KDUMP_CMDLINE_APPEND

[Guilherme G. Piccoli]

Since Xenial release, Ubuntu relies on systemd as its init system - there's a kdump service to prevent some other services to unnecessarily start in kdump environment.

Problem: if we add something to KDUMP_CMDLINE_APPEND, the entry for kdump service, "systemd.unit=kdump-tools.service" is removed from the command-line. The user manually needs to add that, and this seems highly prone to error.

We propose here to decouple the "systemd.unit=kdump-tools.service" parameter from KDUMP_CMDLINE_APPEND, so if user wants really to remove this option, they should used KDUMP_CMDLINE instead.

I'll mark this bug as duplicate from LP #1800566 - we'll track progress only in that bug, the SRU for this will be worked along with the reset_devices thing.

Thanks,

Guilherme

I'm un-marking this as duplicate - LP #1800566 is being worked only for the reset_devices portion, so I'm decoupling both bugs in order we can work this one soon-ish.
Cheers,

Guilherme

The Eoan Ermine has reached end of life, so this bug will not be fixed for that release
