[Nix-dev] nixos-rebuild switch error

[Tilo Schwarz]

Hi,

from time to time I have an error doing "nixos-rebuild switch" (see below,
I stored the last lines including the error messages).

What is strange: If I simply execute above command a second time, the
command succeeds.

Maybe someone has an idea, what could be wrong.

Thank you,
Tilo
