user1790: To enhance my education during the Marlowe Pioneers program (with simultaneous Emurgo Haskell Dev Pro course), I've been running NixOS as my daily driver for full immersion over the past two weeks or so (and loving it).
My google-foo is failing me regarding a declarative installation of the provided daedalus-4.10.0-marlowe_pioneers-21765.bin. While I'd prefer somehow declaring it globally in /etc/nixos/configuration.nix for now, alternative solutions are more than welcome.

user6086: the download is an installer. Running the installer will put an executable in ~/.local/bin/.
When I ran this executable I got an error. It's expecting a file /etc/localtime which I don't have and seems that it isnt standard on nixos.
You can edit this script (~/.local/bin/daedalus-marlowe_pioneers) to work around this.
On line 9 perform the following diff.
- cat /etc/localtime > etc/localtime
+ echo "TZif2UTCTZif2UTC\rUTC0" > etc/localtime

This sets it to utc. I got this off another linux machine
I haven't done any more than launch the app. It does however now launch
