==== Install Nix for a single user ====

Line 21:

After that being done, you can use all Nix commands as a normal user without any special permissions (for example by using <code>sudo</code>)

~~==== Install Nix without root permissions ====~~

~~By using [https://github.com/lethalman/nix-user-chroot nix-user-chroot] or [https://github.com/proot-me/PRoot PRoot]~~

~~you can use Nix on systems, where you have no permission to create `/nix`.~~

~~<code>nix-user-chroot</code> is the preferred and faster option. However it might not run on older linux kernels~~

~~or kernels without user namespace support. With the following command you can test~~

~~whether your system support user namespaces:~~

~~<syntaxHighlight lang="console">~~

~~$ unshare --user --pid echo YES~~

~~</syntaxHighlight>~~

~~The output should be <code>YES</code>.~~

~~If the command is absent an alternative is to check the kernel compile options.~~

~~<syntaxHighlight lang="console">~~

~~$ zgrep CONFIG_USER_NS /proc/config.gz~~

~~# On some systems like Debian or Ubuntu the kernel configuration is in a different place~~

~~$ grep CONFIG_USER_NS /boot/config-$(uname -r)~~

~~</syntaxHighlight>~~

~~If the output of this command is <code>CONFIG_USER_NS=y</code> your system supports user namespaces.~~
