</span>Ok I don't know whether you're having a problem with pstore at c/r or<br>
not as that seems unrelated to the fuse gorp, but if you are having a<br>
problem with pstore, then<br>
<br>
Edit /usr/share/lxc/config/ubuntu.common.conf, comment out<br>
<br>
lxc.mount.entry = /sys/fs/pstore sys/fs/pstore none bind,optional 0 0<br>
<br>
and add<br>
<br>
lxc.mount.entry = tmpfs /sys/fs/pstore none bind,optional 0 0<br>
<br>
That should keep mountall from trying to mount pstore.<br>
<br>
I think what you really want to do is teach criu to simply mark that pstore<br>
was mounted, then simply bind-mount it from the host again at restart.<br>
