Report whether Linux User namespace is enabled by default in the Linux distros
The reason why junest -u is not used as the main backed solution for JuNest is that some Linux distros do not have the linux user namespace enabled by default. It is required to have root privileges in order to enabled it.
Fortunately, in several distros like Ubuntu and Arch Linux it seems they have enabled it by default.
This issue is to report the list of distro which have the namespace enabled by default and decide whether is the right time to have such backend as the primary solution for JuNest and Proot as secondary solution.
Major Distros to look at:
- Ubuntu
- Arch Linux
- Debian
- Fedora
3.16.0-5-amd64 #1 SMP Debian 3.16.51-3+deb8u1 (2018-01-08) x86_64: disabled
Good news! I run provisioned machines in Vagrant on multiple Linux Distros. The user namespace is enabled on most of the distros:
Archlinux
