| crtools || Restore arbitrary mountpoints tree || hard || - || Linux kernel can construct tricky knows with [[mount points]]. We don't support arbitrary configuration of such things, only those that are in active use by software. Need to fix them up.

| crtools || [[Lazy migration]] using userfaultd || medium || xemul || Lazy migration is when we move all the tasks on another node, but leave theirs memory on the source one. Not to allow tasks read garbage from empty address space we protect all of it as inaccessible. When tasks start reading/writing the mem they got page-fault-ed. With the userfaultfd technology it can be possible to intercept the #PF, pull the page from source node and map it into expected address.

| crtools || Dump tasks from cgroup || easy || - || Currently criu dumps a subtree from given pid. It makes sense to request CRIU to dump a set of tasks from given cgroup.
