# Welcome to the top-level default.nix of stockholm.

|
||||
# You can discover the whole thing easily using the `get` utility,
|
||||
# which can be found at http://cgit.cd.krebsco.de/get/tree/get
|
||||
# To install `get` on any Nix-enabled system, use:
|
||||
#
|
||||
# nix-env -f /path/to/stockholm -iA pkgs.get
|
||||
#
|
||||
# The "current" arguments are used to provide information about the user who's
|
||||
# evaluating this file. This information is used to determine which user
|
||||
# namespace is to be used. Of course there's nothing trying to prevent you
|
||||
# from forging this information. E.g. you could try to generate the deployment
|
||||
# script for some random user's system, targeting some random host:
|
||||
#
|
||||
# LOGNAME=tv get krebs.deploy system=nomic target=8.8.8.8
|
||||
#
|
||||
{ current-date ? abort "current-date not defined"
|
||||
, current-host-name ? abort "current-host-name not defined"

, current-user-name ? builtins.getEnv "LOGNAME"
