file-systems: 'file-system-needed-for-boot?' is #t for parents of the store.
Suggested by John Darrington <john@darrington.wattle.id.au>. * gnu/system/file-systems.scm (%not-slash): New variable. (file-prefix?): New procedure. (file-system-needed-for-boot?): Use it to check whether FS holds the store. * tests/file-systems.scm ("file-system-needed-for-boot?"): New test. * gnu/tests/install.scm (%separate-store-os)[file-systems]: Remove 'needed-for-boot?' field for "/gnu".
