* Nasty: Glibc clears the TMPDIR environment variable in setuid
...
programs, so if a builder uses TMPDIR, then it will fail when
executed through nix-setuid-helper. In fact Glibc clears a whole
bunch of variables (see sysdeps/generic/unsecvars.h in the Glibc
sources), but only TMPDIR should matter in practice. As a
workaround, we reinitialise TMPDIR from NIX_BUILD_TOP.

processes before and after the build.

builder under the desired build user.

specified in the setuid config file).

allowed uid is specified in a configuration file in

* Get rid of `build-users'. We'll just take all the members of
...
`build-users-group'. This makes configuration easier: you can just
add users in /etc/group.

* Start of the setuid helper (the program that performs the operations
...
that have to be done as root: running builders under different uids,
changing ownership of build results, and deleting paths in the store
with the wrong ownership).
