Re: [PATCH v2] classes/image-postproc: chroot before postprocessing /etc/machine-id

[Zhihang Wei <wzh@ilbers.de>]

Hi,

The patch previously encountered an error during the full CI run. However,
this error cannot be reproduced after multiple runs on the CI server or 
on my
local machine. We believe the issue is related to the CI itself rather than
the patch.

Since it seems that the next version (v3) is on the way, we’ll wait for it
before running CI again. If that’s not the case, please let me know.

Best regards,
Zhihang
