That's because snapd tickles the kernel in a way that

I think it has to do with nesting kernel structures related to
security (LXD sets those up, then snapd wants to tweak them again),
but a much clearer answer would come from Stephane cc'd.<br>

It works fine if it's not inside a LXD container. Is this an
issue with<br>
LXD or with snapd or am I missing something?<br>
<br>
Also: Why is there an "ugly" \x2d (which seems to be a
hypen-minus) in<br>
the systemd-file rather than a "normal" minus?<br>
<br>
