A couple updates:

• More work was done on separating the evaluation logic from the deployment logic, with the new colmenaHive output being the integration point that ties the two halves together. Colmena can now deploy from the colmenaHive output which should be an already-evaluated hive generated by colmena.lib.makeHive (or your own logic!). Example here. cc David Arnold (blaggacao) Yureka (she/her)
• Flake-enabled deployments now use nix copy and the new SSH store protocol (ssh-ng://) for copying closures to remote hosts.

Looks like this breaks buildOnTarget.

specifically I got this exception:

couldn't execute "pgrep": no such file or directory
    while executing

    (procedure "get_child_pid" line 4)
    invoked from within

which does:

    if {[file exists "/usr/bin/pgrep"]} {
        set fd [open "|pgrep -P $pid" "r"]
        set child_pid [string trim [lindex [split [read $fd] \n] 0]]
    } else {
        set fd [open "|ps --ppid $pid -o pid" "r"]
        set child_pid [string trim [lindex [split [read $fd] \n] 1]]
    }

I have another request: In flake-enabled deployments, can we pass the nixpkgs flake so that the hive expression can use nixpkgs.lib.nixosSystem and get the proper system.nixos.(revision|versionSuffix)?

In reply to @rendakuenthusiast:imperishable.name
this is basically a failure of hermeticism, right? the redis build was happening on my system and it has one bit of source code that looks at /usr/bin/pgrep. is there a principled way in nix to make that not visible to derivations being built?

In reply to @rendakuenthusiast:imperishable.name
and when colmena tries to deploy from my laptop, I have /usr/bin/pgrep installed at that path in my normal OS
