Workaround for LP#1712808?

[Paul Goins]

Charms building upon layer-snap, when deployed to privileged LXD containers, can run into bug https://pad.lv/1712808.
(Concrete example: https://pastebin.ubuntu.com/p/sYz9h5frDF/)

As that bug has been open for quite some time, I'm being forced to work around it via the retry method - in my case, trying to install "core" first, ignoring any errors, then installing the snaps that I care about.

This means that while I can use layer-snap for its infrastructure, I am removing my list of snaps to install from layer.yaml and am calling snap.install() during my install hook.

As https://pad.lv/1712808 has been around for some time now - should we consider adding a workaround to layer-snap so things "just work"? Or would that be encouraging bad practices and instead we should handle this on a case-by-case basis like I'm doing now?

Thanks for your attention.
