== Security ==
Due to restrictions imposed by several kernel APIs CRIU uses, the tools can only work with run with root privileges. However, if the node administrator sets the +suid bit on the criu binary, criu will be able to work when launched from regular user. But, in the latter case, criu will refuse to dump or restore processes whose <code>[se]?[ug]id</code> is not equal to the corresponding value of the calling user.
