Comment 26 for bug 1945697

To be clear, there are two "fixes" here:

1. My fix to the underlying mount namespace code which is immediately causing a crash in firefox whenever a content snap or snapd itself is refreshed. That is under review here: https://github.com/snapcore/snapd/pull/10676 and is due to be released for snapd 2.55 (we will not release 2.55 without this fix).

2. The more general fix to prevent refreshes of snaps in general when they are being used is refresh app awareness and that is orthogonal to the fix I mentioned above. Pawel has posted the final call for testing of the feature at https://forum.snapcraft.io/t/refresh-app-awareness-call-for-testing/29123 so providing positive feedback that the feature works in preventing issues there would be appreciated as well as other issues or questions about the feature. I don't consider this specific launchpad bug to be about enabling refresh app awareness FWIW, I believe we have another bug "tracking" that, but regardless, enabling it by default is very high on our priority for 22.04.

Thanks,
Ian
