DavHau / nix-portable

If user namespaces are not available on a system, nix-portable will fall back to using proot instead of bubblewrap. Proot's virtualization can have a significant performance overhead depending on the workload. In that situation, it might be beneficial to use a remote builder or alternatively build the derivations on another host and sync them via a cache like cachix.org.

All programs installed via nix-portable will only work inside the wrapped environment. To enter the wrapped environment just use nix-shell:

bwrap is preferred over proot and existing installations are preferred over the nix-portable included binaries. nix-portable will try to figure out which runtime is best for your system. In case the automatically selected runtime doesn't work, use the follwing environment variables to specify the runtime, but pleaae also open an issue, so we can improve the automatic selection.
