| crtools || optimize kcmp calls || - || For fs/fdt/vm/etc we can pre-generate ID based on objects that live on them. If pre-ID matches, then call kcmp.

| crtools || TCP socket migration with changed IP || - ||  it might make sense to migrate a tcp connection on a box with changed IP address _if_ both boxes are NAT-ed to the destination. We will then have to go to NAT box and fix the conntracks, but this might make sense.

| crtools || [[Applying images]] || xemul@ w/ students || Think about ability to take images and apply them to a living task(s). E.g. -- repopulate fdtable according to data from image. Another use-case -- when doing partial migration we'll need to modify one part to switch from pipes to sockets

| crtools || Shared objects (mm/fs) support || - || Now we have the kcmp syscall and can do it. The first candidate is mm sharing, as we do know, that MySQL does so sometimes.

| crtools || Smart paths resolution || - || Need a way to resolve paths to overmounted files. There are two ways: 1. Move mounts, that overlap the desired path temprarily. 2. When creating a new mount pre-open an fd keeping the mountpoint. Later, do accurate path resolve and call openat() on proper mountpoint fd
