Rollback is not executable on MacOS

Hey there,

So it seems the permissions for executing a rollback seem to be wrongly configured.

sudo nix run .#rollback leads to:

Running rollback for aarch64-darwin /nix/store/apw6xiz22d4hr5rz687yvy4v0nih23jd-rollback/bin/rollback: line 4: /nix/store/hcf07hxx5bdgzzfn85184zsd8sdan8is-source/apps/aarch64-darwin/rollback: Permission denied /nix/store/apw6xiz22d4hr5rz687yvy4v0nih23jd-rollback/bin/rollback: line 4: exec: /nix/store/hcf07hxx5bdgzzfn85184zsd8sdan8is-source/apps/aarch64-darwin/rollback: cannot execute: Undefined error: 0

When i look at the permissions of each of the management commands, I discovered:

-r-xr-xr-x 1 root nixbld 4746 Jan 1 1970 apply -r-xr-xr-x 1 root nixbld 431 Jan 1 1970 build -r-xr-xr-x 1 root nixbld 550 Jan 1 1970 build-switch -r--r--r-- 1 root nixbld 609 Jan 1 1970 rollback

Which indicates, no user is able to run the rollback. Would it mess with the config if I manually chmod the permissions to be the same as for the other scripts?
Also is there any point, this is configured in the setup? I haven't managed to find anything hinting that way...

Is this a me problem, or can someone else replicate the problem?

Cheers!

Found the solution, there is a small error in the README, preventing the rollback from being executable later on.

Step 4 of the README to make apps executable is missing the rollback. So instead of:

find apps/$(uname -m | sed 's/arm64/aarch64/')-darwin -type f \( -name apply -o -name build -o -name build-switch -o -name create-keys -o -name copy-keys -o -name check-keys \) -exec chmod +x {} \;

the correct command should be:

find apps/$(uname -m | sed 's/arm64/aarch64/')-darwin -type f \( -name apply -o -name build -o -name build-switch -o -name create-keys -o -name copy-keys -o -name check-keys -o -name rollback \) -exec chmod +x {} \;

Can't PR without forking unfortunately, so I'll leave that to the owner!

@dustinlyons Just so you know, that's what's causing the problem (:
