Same thing on Linux. If you update the systemd configuration to remove the debug flag, it'll get added back in on the next reboot. I also couldn't find a setting in /etc/default/keybase that would disable this either.

@docsmooth

Use systemd drop-in units instead.

For example, systemctl --user edit keybase, and add

[Service]
ExecStart=
ExecStart=keybase --use-default-log-file service

, and systemctl --user edit kbfs, and add

[Service]
ExecStart=
ExecStart=kbfsfuse -log-to-file

Note this is unsupported and we won't be able to help you if you run into issues (unless you turn on logs again and reproduce the bug).

(I've updated these to remove only debugging)

I don't want to disable all logging, because I want to catch errors. I just don't want debug logging. Debug logging on a laptop eats up measurable battery life (keybase is consistently higher than chrome, unless I simply remove "debug" from the systemd config).

You can do that with drop-in units too. See https://askubuntu.com/a/659268.

So that anyone reading the thread isn't confused: #3155 (comment) (including @heronhaye 's edit) does work, and survives both reboots and updates to keybase (tested on Ubuntu 19.04)

Any updates on how to resolve this on macOS?

@heronhaye Can this be done in Windows as well?
I tried to start keybase with keybase --no-debug ctl start.
The process then shows to be started with both debug flags (--no-debug --debug).
But even though the documentation (keybase help advanced) says that no-debug takes precedence over debug it still writes debug messages to log.

Piping in a bit late, but I wonder as well how it's done under macOS. Same reason as @docsmooth — even though I haven't noticed much of a battery drain myself, but it's a question of not wasting resources — I'm not actively developing anything on top of Keybase (yet!) so I don't really need to deal with debugging logs, for now.

Thanks for the systemd drop-in units tip, though; they're cool for the many devices and servers I've got around the world which do use systemd (as opposed to Apple's own launchd which predates systemd and inspired it, but is not quite the same thing...).
