Chroot/Jails alternative available for Devuan

Hi there,

I am wondering if there are available for Devuan, besides CHROOT, other technologies closer to the BSD JAILS or NSPAWN provided by Systemd, thanks! 🙏

Looks like systemd-nspawn is a wrapper around the kernel namespaces feature.

Linux namespaces do NOT require systemd to use.

Thank you for the head-up, your suggestion landed me on this old article:

https://lwn.net/Articles/531114/

I think they had better to rename the project from SYSTEMD to SYSTEMNIH...

😂

You might want to look at overlay-boot from devuan/experimental for light-weight container-like hosts using linux namespaces. I.e. sharing the kernel by virtual hosts. (Source at https://git.devuan.org/devuan/overlay-boot)

I'm also exploring user-mode-linux for non-root pseudo-virtualization; separate kernels on the host's hardware (not virtualized). This includes the variant where the VM file system is a host directory. (see https://git.devuan.org/rrq/umlvm)

Thank you because, I read several article about the topics and namespaces aren't meant to persistent, also are pretty trickery and require knowledge that I miss completely.

Yes, everything is complicated in its particulars. That's why it's fun to learn stuff.
