[Nix-dev] umask and rebuild switch

[Lluís Batlle i Rossell]

Hello,

I screwed quite enough things today...

I was running a root shell with "umask 200", and I typed: nixos-rebuild switch

That made all my /var/setuid-wrappers with bad permissions for the ".real"
files, namely "600", and things like sendmail (owned by nobody) couldn't read
the '.real' file, and failed. No mail.

Maybe the activation script should send the umask?

Regards,
Lluís.
