But aren't snaps running inside chroots? Why does "/etc" refer to the
system /etc instead of the /etc inside the snap chroot? Am I
understanding correctly that snaps bindmount the system /etc into the
snap chroot and then don't provide any permission to read anything in
there?

I think it would be nice if "/etc" was just inside my snap chroot and
my snap thus had total ownership of the entire dir.

Yeah this seems like a more reasonable approach, thanks.
