</span>Ah I see. In the upstream kernel fuse and fusectl are not virtualized. So<br>
the latter fs when mounted inside container reveals fuse mounts from all<br>
the system. And criu fails to dump one, though none of the connections<br>
seen inside fusectl belong to this container.<br>
<br>
Serge, Tycho, do you have any ideas what can we do about it?<br>
<br>
Thouraya, I think for your experiments you can just umount the fusectl fs.<br>
<br>
Thanks,<br>
