sh <(curl -L https://nixos.org/nix/install) --darwin-use-unencrypted-nix-store-volume
works great. you can see /nix is mounted
ec2-user@ip-10-249-8-250 ~ % nix --version
nix (Nix) 2.3.10

Problem
however when I reboot the nix vol didn't auto mount (maybe /etc/fstab is no longer used by Catalina?)
and /nix is now own by root

mount_apfs: volume could not be mounted: Operation not permitted
mount: / failed with 77
mount_apfs: volume could not be mounted: Operation not permitted
mount: /nix failed with 77
I can get around it by sudo mount_apfs disk2s6 /nix but
I am using these mac ec2 instance for CI purpose and the process would fail
due to /Users/ec2-user/.nix-profile/etc/profile.d/nix.sh: Operation not permitted
Steps To Reproduce
described above
Expected behavior
nix vol mounted when boot and /nix owned by user who executed the install scripted
nix-env --version output
nix (Nix) 2.3.10
Additional context
I am running these on aws ec2 Mac1.metal instances
