ssh-copy-id failing: Too many arguments

### Prerequisites - [x] I have updated to the latest version using `nix run --refresh github:nix-community/nixos-anywhere` - [x] I have reproduced the issue with the `--debug` flag - [x] I have searched existing issues to make sure this isn't a duplicate ### Bug Description I'm trying to run nixos-anywhere but I keep getting `Too many arguments` errors by `ssh-copy-id` which seem to have to do with the usage of the `-i` flag. It works when I return to OpenSSH 9.6 I haven't figured out yet if this has to do with how nixos-anywhere uses ssh-copy-id or if it's a bug in `ssh-copy-id`. ### Steps to Reproduce ```bash ssh-copy-id -xn -i /tmp/test-nixos-anywhere ubuntu@10.10.10.210 ``` If I omit the `-i` flag and its argument, `ssh-copy-id` works. ### Debug Logs ```shell […] + sshUser=ubuntu + sshHost=10.10.10.210 + [[ 1 != 1 ]] + uploadSshKey + local sshCopyHome=/home/basbebe + mkdir -p /home/basbebe/.ssh/ + [[ -n '' ]] + ssh-keygen -t ed25519 -f /tmp/tmp.uBH8XwkMQb/nixos-anywhere -P '' -C nixos-anywhere + step Uploading install SSH keys + echo '### Uploading install SSH keys ###' ### Uploading install SSH keys ### + [[ n == y ]] + HOME=/home/basbebe + ssh-copy-id -o IdentitiesOnly=no -o ConnectTimeout=10 -o IdentitiesOnly=yes -i /tmp/tmp.uBH8XwkMQb/nixos-anywhere -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o AddKeysToAgent=yes ubuntu@10.10.10.210 /run/current-system/sw/bin/ssh-copy-id: ERROR: Too many arguments.
