libcriu-dev - 4.1-1 main

criu contains the utilities to checkpoint and restore processes in
userspace.
.
It can freeze a running container (or an individual application) and checkpoint
its state to disk. The data saved can be used to restore the application and
run it exactly as it was during the time of the freeze. Using this
functionality, application or container live migration, snapshots, remote
debugging, and many other things are now possible.
.
This package provides the criu development headers.
