Both the teleport and temporal-cli packages include an executable named `tctl` and attempting to install them both into the same environment results in this error:

```auto
environment> error: collision between `/nix/store/aw9zjxk0s7k0l2l1sx8lrs9ms4acihxj-temporal-cli-1.18.0/bin/tctl' and `/nix/store/ak4nmpqijdvj3kf5gq1j8a2vy9cnz24i-teleport-14.3.0/bin/tctl'

```

Is there any way to work around this? Can flox be configured to rename the symlink to the /nix/store path for one of the packages to something else?

I found [How to solve a collision error when installing some packages](https://discourse.flox.dev/t/how-to-solve-a-collision-error-when-installing-some-packages/673) for a similar sounding error but that looks like it was a bug that doesn’t apply here.

You can add a priority for each package, e.g. if you want `teleport` to win you could say:  
`teleport.priority = 1`

The default priority is 5. Packages with a lower `priority` value will take precedence over packages with higher `priority` values.
