Allow specifying hostname when backing up

[askielboe]

Would be nice to be able to configure the --host argument to the backup command.

My shell (zsh on macos) has a HOST environment variable, so an easy fix for me is to simply add --host "$HOST" \ to the backup command, and then exporting HOST in the runner config file. This is probably not portable though.

Hi,

That's interesting: does Restic not pick up the hostname automatically?

Maybe what we need is a way to specify extra arbitrary options to commands.

By the way, do you mean --hostname? That's what I see in restic help backup.

Hey. Thanks for responding to this.

As of restic 0.9.3 --hostname is deprecated in favor of --host. See the changelog.

If no --host is specified when backing up restic uses os.Hostname(). I'm not sure if that can be changed in the environment somehow, but I think it would probably be better if restic-runner supported the --host argument somehow.

I like the idea of extra arbitrary commands. As long as it can be set in the config files.
