Libvirt now tries to preserve all mounts under /dev in qemu
namespaces.
The old rules only listed a set of known paths but those are no more
enough.
I found some due to containers like /dev/.lxc/* and such but also
/dev/console
and /dev/net/tun.
Libvirt is correct to do so, but we can no more predict the names
properly, so
we modify the rule to allow a wildcard based pattern matching what
libvirt does.

What are you trying to convey with this rule? As written, the '{/,}' is
redundant since '**' will match that.
+ mount options=(rw, move) /{var/,}run/libvirt/qemu/*.dev/ ->
/dev/,
+ mount options=(rw, move) /{var/,}run/libvirt/qemu/*{/,} ->
/dev/**{/,},
ditto
