Petitboot ignores enabled autoload?

[Fredrik Noring]

Hi,

I recently installed a Petitboot v1.7.1-p836d356 configuration running under
Skiroot and stumbled on some difficulties:

Autoload is enabled and set to 10 s but somehow Petitboot seems to ignore
this and nothing happens. I've attached pb-discover.log below. What could
be the problem? (Is Petitboot supposed to make use of the "default" label
in kboot.conf, by the way?)

Gentoo is installed on the root filesystem. The installation process was
quite problematic with Petitboot running the background, because its
device discovery mechanisms interact badly when creating and configuring
new filesystems in the shell. I had several failures of various kinds in
addition to a complete filesystem corruption (block I/O device errors)
before the installation could be completed. Is there a reasonable way to
turn off Petitboot when working with devices in the shell?

What is the most reliable way to write changes to a device? According to

https://sthbrx.github.io/blog/2016/08/17/getting-in-sync/

one could use "pb-event sync@<device>". However, this command seems to
accept nonexistent devices, which means that if there is a misunderstanding
on the naming, one can easily have the (incorrect) impression that changes
are properly written to the device, only to later discover that everything
was lost after rebooting.
