Comment 1 for bug 1654642

I'm not sure of the long term goals of the classic snap but there are several options on how to fix this for the current situation:

1. add a 'classic' interface that adds rules like those in the workaround and have the classic snap 'plugs: [ classic ]'
2. special case the classic snap in snapd and add rules like those in the workaround unconditionally
3. use 'confinement: classic' for the classic snap

'3' seems like the cleanest way to do this but someone would have to confirm that using 'classic' confinement does what you want for this snap since the mount namespace setup that is used with strict and devmode isn't present with 'classic' confinement (but since 'chroot' is used I suspect that is probably ok).
