✨ CRIU-NS ✨

okay so bestie, welcome to criu-ns — the CRIU wrapper that runs criu in a whole new namespace situation 💅 (that's the manual name btw, it's literally criu-ns from the CRIU manual, iykyk 🦋)

🎀 SYNOPSIS 🎀

like, here's how you actually call her:

criu-ns dump -t PID [<options>]
criu-ns pre-dump -t PID [<options>]
criu-ns restore [<options>]
criu-ns check [<options>]

💖 DESCRIPTION 💖

so criu-ns runs criu inside a new PID namespace and a new mount namespace ✨ two for one, we love to see it.

and why, you ask? 🫶 because sometimes you gotta restore a process tree that needs one specific PID — and that PID is already taken on the system 😭 the way that ruins your whole afternoon. this here wrapper script exists to fix exactly that, and the girlies call it the "PID mismatch" problem 🔥

👑 SEE ALSO 👑

go read these, they're giving main character energy:

The CRIU team 💜 (icons, every single one of them)

ok that's the whole page bestie, go forth and restore your process trees 🌈💀

signed, sealed, delivered with love — this was criu version 4.2.1, dated 07/21/2026, and yes the manual itself is CRIU-NS(1) 🎀✨🦋
