How do you set ZBM parameters?

[descendingnerdliness]

I have just installed ZBM for the first time relying upon "Complete beginner's guide to installing ZFSBootMenu". After solving a few problems, I have ZBM booting Debian Testing on ZFS and it looks great. Thank you.
The issue is that ZBM.Timeout seems to default to -1, and sits forever waiting for a \n.
The man page explains that I need to set ZBM.Timeout=5, or something, to have it boot without further intervention. But the obscurity is in how one would do that. Is there a config file somewhere? I would really appreciate clear directions and examples. Thank you.

Please link the exact guide that you followed; ZFSBootMenu defaults to a 10 second timeout. There are too many ways to install it to say conclusively how you're getting a timeout of -1.

You probably just forgot to set bootfs on the pool.

Thanks for the replies. The Guide is here https://github.com/zbm-dev/zfsbootmenu/wiki/Complete-beginner's-guide-to-installing-ZFSBootMenu#334-start-the-new-environment-enter-any-encryption-password-and-select-your-boot-envrionment-in-zfsbootmenu.

As for bootfs and the other parameters, it is really unclear in the docs how they are set. But there is no mention of bootfs in the guide.

that guide is unofficial and there is an official debian install guide on the official docs: https://docs.zfsbootmenu.org/en/v2.2.x/guides/debian.html

Thanks. That guide does include the bootfs parameter, which I can probably figure out how to set with the command supplied there. But since my system boots when I press enter, what I really need to know is how to set the ZBM.Timeout parameter.

Were you able to get everything working on your system?

The bootfs property is intrinsic to ZFS. See zpoolprop(7) for more details.

Parameters for ZFSBootMenu are set on its kernel command-line as documented on zfsbootmenu.7. If you are using a pre-built UEFI executable, you can use the zbm-kcl(8) tool to modify the command-line, as well as adjust your boot environment's command line. The tool can be fetched at https://get.zfsbootmenu.org/zbm-kcl and is a standalone utility, although it needs access to the objcopy executable to manipulate the UEFI bundle.

As for the timeout, the default is 10 seconds. The timeout is ignored when you don't set bootfs because ZBM never tries to guess your intent. Set the property and the default countdown should take effect.
