Re: GSoC 2026: Interest in Files on Detach mounts project

Hello Boluwatife,

This project is in done stage already.

Sorry, it was removed from "Google Summer of Code Ideas" page only yesterday, that might've lead to confusion.

Please consider other project ideas at https://criu.org/index.php?title=Google_Summer_of_Code_Ideas.

Pavel.

I have spent the past few days setting up the development environment on Ubuntu 24.04, successfully built CRIU v4.2 from source on the criu-dev branch, and performed my first checkpoint/restore of a basic process.

I have also started reading through criu/files-reg.c and criu/mount.c to understand how file descriptors and mounts are currently handled.
