Question 1

Does Lxroot require sudo or root access?

Accepted Answer

No, Lxroot is designed for non-root users by leveraging Linux namespaces, allowing you to create and run isolated environments without administrative privileges, as highlighted in the description.

Question 2

What Linux kernel version do I need for Lxroot?

Accepted Answer

You need Linux kernel 3.9 or later, and preferably 5.11+ for overlay filesystem support. Unprivileged namespace support must be compiled into the kernel and enabled at runtime, as noted in the README requirements.

Question 3

How to create an Alpine Linux world with Lxroot?

Accepted Answer

Manually create directories, extract the Alpine minirootfs, and use lxroot to enter, as shown in the README example. However, the helper script mk-alpine.sh is not yet published, so setup requires more steps.

Question 4

Can Lxroot isolate network connections or just the filesystem?

Accepted Answer

Lxroot primarily focuses on filesystem isolation using chroot and namespaces; it does not provide built-in network isolation, so for full container-like features, you'd need additional tools.

Question 5

Is Lxroot or Docker better for lightweight containers?

Accepted Answer

Lxroot is lighter and doesn't require root or a daemon, ideal for simple isolation tasks. Docker offers more features like networking, image layers, and a larger ecosystem, so choose based on complexity needs.

Question 6

How do I share my home directory between Lxroot worlds?

Accepted Answer

Use symbolic links for directories like home, as Lxroot supports bind-mounting them into newroot. This allows shared access across multiple worlds without duplicating data, per the README.
