Enroot installation on Alinux2

[hgreebe]

Is it possible to install enroot with a Alinux2 OS. Some of the runtime dependencies such as fuse-overlayfs do not exist in the alinux2 repo.

Additionally the installation doc only gives a download link for el8 and not el7: https://github.com/NVIDIA/enroot/releases/download/v3.5.0/enroot-3.5.0-1.el8.${arch}.rpm

So I was wondering if enroot could be used with the Alinux2 OS.

I don't think we have tested Alinux2 recently, but fuse-overlayfs is an optional dependency so that's fine on this side.

From a quick experiment within a amazonlinux:2 container, it works fine when using the published el8 enroot package:

$ docker run --privileged -ti amazonlinux:2

bash-4.2# amazon-linux-extras install epel -y

bash-4.2# yum install -y jq squashfs-tools parallel parallel gzip shadow-utils tar util-linux zstd procps

bash-4.2# curl -fSsL -OO https://github.com/NVIDIA/enroot/releases/download/v3.5.0/{enroot-3.5.0-1.el8.x86_64.rpm,enroot+caps-3.5.0-1.el8.x86_64.rpm}

bash-4.2# rpm -i enroot-3.5.0-1.el8.x86_64.rpm enroot+caps-3.5.0-1.el8.x86_64.rpm

bash-4.2# enroot import docker://ubuntu:22.04

bash-4.2# enroot create ubuntu+22.04.sqsh

bash-4.2# enroot start ubuntu+22.04 cat /etc/os-release
