+ macOS Installation + + + Starting with macOS 10.15 (Catalina), the root filesystem is read-only. + This means /nix can no longer live on your system + volume, and that you'll need a workaround to install Nix. + + + + The recommended approach, which creates an unencrypted APFS volume + for your Nix store and a "synthetic" empty directory to mount it + over at /nix, is least likely to impair Nix + or your system. + + + + With all separate-volume approaches, it's possible something on + your system (particularly daemons/services and restored apps) may + need access to your Nix store before the volume is mounted. Adding + additional encryption makes this more likely. + + + + If you're using a recent Mac with a + T2 chip, + your drive will still be encrypted at rest (in which case "unencrypted" + is a bit of a misnomer). To use this approach, just install Nix with: + + + $ sh <(curl https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume + + + If you don't like the sound of this, you'll want to weigh the + other approaches and tradeoffs detailed in this section. + + + + Eventual solutions? + + All of the known workarounds have drawbacks, but we hope + better solutions will be available in the future. Some that + we have our eye on are: + + + + + A true firmlink would enable the Nix store to live on the + primary data volume without the build problems caused by + the symlink approach. End users cannot currently + create true firmlinks. + + + + + If the Nix store volume shared FileVault encryption + with the primary data volume (probably by using the same + volume group and role), FileVault encryption could be + easily supported by the installer without requiring + manual setup by each user. + + + + + +
+ Change the Nix store path prefix + + Changing the default prefix for the Nix store is a simple + approach which enables you to leave it on your root volume, + where it can take full advantage of FileVault encryption if + enabled. Unfortunately, this approach also opts your device out + of some benefits that are enabled by using the same prefix + across systems: + + + + + Your system won't be able to take advantage of the binary + cache (unless someone is able to stand up and support + duplicate caching infrastructure), which means you'll + spend more time waiting for builds. + + + + + It's harder to build and deploy packages to Linux systems. + + + + + + + + It would also possible (and often requested) to just apply this + change ecosystem-wide, but it's an intrusive process that has + side effects we want to avoid for now. + + + + +
+ +
+ Use a separate encrypted volume + + If you like, you can also add encryption to the recommended + approach taken by the installer. You can do this by pre-creating + an encrypted volume before you run the installer--or you can + run the installer and encrypt the volume it creates later. + + + + In either case, adding encryption to a second volume isn't quite + as simple as enabling FileVault for your boot volume. Before you + dive in, there are a few things to weigh: + + + + + The additional volume won't be encrypted with your existing + FileVault key, so you'll need another mechanism to decrypt + the volume. + + + + + You can store the password in Keychain to automatically + decrypt the volume on boot--but it'll have to wait on Keychain + and may not mount before your GUI apps restore. If any of + your launchd agents or apps depend on Nix-installed software + (for example, if you use a Nix-installed login shell), the + restore may fail or break. + + + On a case-by-case basis, you may be able to work around this + problem by using wait4path to block + execution until your executable is available. + + + It's also possible to decrypt and mount the volume earlier + with a login hook--but this mechanism appears to be + deprecated and its future is unclear. + + + + + You can hard-code the password in the clear, so that your + store volume can be decrypted before Keychain is available. + + + + + If you are comfortable navigating these tradeoffs, you can encrypt the volume with + something along the lines of: + + + + alice$ diskutil apfs enableFileVault /nix -user disk + + +
+ +
+ + Symlink the Nix store to a custom location + + Another simple approach is using /etc/synthetic.conf + to symlink the Nix store to the data volume. This option also + enables your store to share any configured FileVault encryption. + Unfortunately, builds that resolve the symlink may leak the + canonical path or even fail. + + + Because of these downsides, we can't recommend this approach. + + +
+ +
+ Notes on the recommended approach + + This section goes into a little more detail on the recommended + approach. You don't need to understand it to run the installer, + but it can serve as a helpful reference if you run into trouble. + + + + + In order to compose user-writable locations into the new + read-only system root, Apple introduced a new concept called + firmlinks, which it describes as a + "bi-directional wormhole" between two filesystems. You can + see the current firmlinks in /usr/share/firmlinks. + Unfortunately, firmlinks aren't (currently?) user-configurable. + + + + For special cases like NFS mount points or package manager roots, + synthetic.conf(5) + supports limited user-controlled file-creation (of symlinks, + and synthetic empty directories) at /. + To create a synthetic empty directory for mounting at /nix, + add the following line to /etc/synthetic.conf + (create it if necessary): + + + nix + + + + + This configuration is applied at boot time, but you can use + apfs.util to trigger creation (not deletion) + of new entries without a reboot: + + + alice$ /System/Library/Filesystems/apfs.fs/Contents/Resources/apfs.util -B + + + + + Create the new APFS volume with diskutil: + + + alice$ sudo diskutil apfs addVolume diskX APFS 'Nix Store' -mountpoint /nix + + + + + Using vifs, add the new mount to + /etc/fstab.
