overlayroot-chroot(8)

✨ NAME ✨

Okay so this is overlayroot-chroot(8) from the initramfs-tools-overlayroot package 💖 and it's all about overlayroot-chroot, which lets you chroot into the lower filesystem in a writable mode 🦋

💜 SYNOPSIS 💜

overlayroot-chroot [COMMAND [ARG]...]

🎀 DESCRIPTION 🎀

Okay bestie, overlayroot-chroot is literally the program you want when you need to get into the lower filesystem and actually write to it 😭 It sets up bind mounts for /proc, /run, and /sys, then remounts the lower directory in an overlayfs with write capabilities, and then it chroots(8) you right into it 💅 When you exit, the bind mounts get unmounted automatically, so everything gets cleaned up behind you ✨

Any [COMMAND [ARG]...] you give it gets passed straight through to chroot(8), so you can run a specific command instead of just hanging out in a shell 🧚

🌸 SEE ALSO 🌸

chroot(8) is the one to check out next, it's the whole engine behind this 🔥
