file-systems: Remove 'title' field and add <file-system-label>.
The 'title' field was easily overlooked and was an endless source of confusion. Now, the value of the 'device' field is self-contained. * gnu/system/file-systems.scm (<file-system>): Change constructor name to '%file-system'. [title]: Remove. (<file-system-label>): New record type with printer. (report-deprecation, device-expression) (process-file-system-declaration, file-system): New macros. (file-system-title): New procedure. (file-system->spec, spec->file-system): Adjust to handle <file-system-label>. * gnu/system.scm (bootable-kernel-arguments): Add case for 'file-system-label?'. (read-boot-parameters): Likewise. (mapped-device-user): Avoid 'file-system-title'. (fs->boot-device): Remove. (operating-system-boot-parameters): Use 'file-system-device' instead of 'fs->boot-device'. (device->sexp): Add case for 'file-system-label?'. * gnu/bootloader/grub.scm (grub-root-search): Add case for 'file-system-label?'. * gnu/system/examples/bare-bones.tmpl, gnu/system/examples/beaglebone-black.tmpl, gnu/system/examples/lightweight-desktop.tmpl, gnu/system/examples/vm-image.tmpl: Remove uses of 'title'. * gnu/system/vm.scm (virtualized-operating-system): Remove uses of 'file-system-title'. * guix/scripts/system.scm (check-file-system-availability): Likewise, and adjust fix-it hint. (check-initrd-modules)[file-system-/dev]: Likewise. * gnu/build/file-systems.scm (canonicalize-device-spec): Remove 'title' parameter. [canonical-title]: Remove. Match on SPEC's type rather than on CANONICAL-TITLE. (mount-file-system): Adjust caller. * gnu/build/linux-boot.scm (boot-system): Interpret ROOT here. * gnu/services/base.scm (file-system->fstab-entry): Remove use of 'file-system-title'. * doc/guix.texi (File Systems): Remove documentation of the 'title' field. Rewrite documentation of 'device' and document 'file-system-label'.
