* Add indirect root registration to the protocol so that unprivileged processes can register indirect roots. Of course, there is still the problem that the garbage collector can only read the targets of the indirect roots when it's running as root... 2006-12-05 00:29:16 +01:00			`wopAddIndirectRoot,`

* Allow unprivileged users to run the garbage collector and to do `nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well. 2006-12-05 03:18:46 +01:00			`wopCollectGarbage,`

* `nix-store --import' now also works in remote mode. The worker always requires a signature on the archive. This is to ensure that unprivileged users cannot add Trojan horses to the Nix store. 2007-02-21 18:34:02 +01:00			`#define STDERR_READ 0x64617461 // data needed from source`
