[Nix-dev] NixOps failes to deploy: bash: Argument list too long

[4levels]

Hi Profpatch,

Thanks for your reply, but I don't know how to even try implementing your
suggestions. This file is generated by NixOps and is run just before the
actual deployment starts. This is at the end of the build phase before the
actual deploy. It starts with

Derive([("out","/nix/store/j9p5zwqj03nq4f4id5a0phig5gk0snqd-nixos-system-secure-16.09pre-git","","")],
...

I have literally no idea where to look or what to change in NixOps itself
to use the suggestions you made, as this goes way beyond my nix-knowledge.
For all I know, this issue could come from something totally different as
well, I'm just gessing here since this is the last output of the nixops
deploy call before the error message. Below the full output of the call

[erik at no01:~]$ nixops deploy --build-only --show-trace
building all machine configurations...
these derivations will be built:

/nix/store/wz9mvb6x082h4mvww1gsf0x0l9fq8p7z-nixos-system-secure-16.09pre-git.drv
  /nix/store/bz3ajdlxalr0c8i1zik40zwvnsb2g8a7-nixops-machines.drv

while setting up the build environment: executing

Kind regards,

Erik
