system: Add '%devtmpfs-file-system' for udev, and '%base-file-systems'.
Suggested by Adam Pribyl <pribyl@lowlevel.cz>. * gnu/services/base.scm (udev-service)[requirement]: Add 'file-system-/dev'. * gnu/system/file-systems.scm (%devtmpfs-file-system, %base-file-systems): New variables. * gnu/system/install.scm (installation-services)[file-systems]: Use %base-file-systems. * build-aux/hydra/demo-os.scm (file-systems): Likewise. * doc/guix.texi (System Installation): Show %BASE-FILE-SYSTEMS in the example. (Using the Configuration System): Likewise. (File Systems): Document %base-file-systems, %devtmpfs-file-system, %binary-format-file-system, and %fuse-control-file-system.
