Many thanks to Reepca Russelstein for their review and guidance on these
changes.
* nix/libstore/build.cc (guestUID, guestGID): New variables.
(DerivationGoal)[readiness]: New field.
(initializeUserNamespace): New function.
(DerivationGoal::runChild): When ‘readiness.readSide’ is positive, read
from it.
(DerivationGoal::startBuilder): Call ‘chown’
only when ‘buildUser.enabled()’ is true. Pass CLONE_NEWUSER to ‘clone’
when ‘buildUser.enabled()’ is false or not running as root. Retry
‘clone’ without CLONE_NEWUSER upon EPERM.
(DerivationGoal::registerOutputs): Make ‘actualPath’ writable before
‘rename’.
(DerivationGoal::deleteTmpDir): Catch ‘SysError’ around ‘_chown’ call.
* nix/libstore/local-store.cc (LocalStore::createUser): Do nothing if
‘dirs’ already exists. Warn instead of failing when failing to chown
‘dir’.
* guix/substitutes.scm (%narinfo-cache-directory): Check for
‘_NIX_OPTIONS’ rather than getuid() == 0 to determine the cache
location.
* doc/guix.texi (Build Environment Setup): Reorganize a bit. Add
section headings “Daemon Running as Root” and “The Isolated Build
Environment”. Add “Daemon Running Without Privileges” subsection.
Remove paragraph about ‘--disable-chroot’.
(Invoking guix-daemon): Warn against ‘--disable-chroot’ and explain why.
* tests/derivations.scm ("builder is outside the store"): New test.
