the kernel Linux command-line parameters.

and '--system' to 'gnu.load', 'gnu.repl', 'root' and 'gnu.system',

services: Prevent following symlinks during activation.
This addresses a potential security issue, where a compromised
service could trick the activation code in changing the permissions,
owner and group of arbitrary files.  However, this patch is
currently only a partial fix, due to a TOCTTOU (time-of-check to
time-of-use) race, which can be fixed once guile has bindings
to openat and friends.

Fixes: <https://lists.gnu.org/archive/html/guix-devel/2021-01/msg00388.html>

* gnu/build/activation.scm: new procedure 'mkdir-p/perms'.

activation: Shared system home directories are now 555 and root-owned.
Fixes <https://bugs.gnu.org/34788>.
Reported by Jack Hill <jackhill@jackhill.us>.

Regression introduced by the combination of
8bb76f3d44c1f5ffec8011819494db306a51d801 and
0ae735bcc8ff7fdc89d67b492bdee9091ee19e86: /var/empty would be 700 and
owned by one of the system accounts (thus inaccessible to others), and
/var/run/dbus would be 700 as well, thereby preventing D-Bus clients
from connecting to the daemon.
