bug#40998: [PATCH 1/3] initrd: Rename the '--root' initrd option to just 'root'. |

This is to make it less surprising, given the common convention sets forth by
the kernel Linux command-line parameters.
* gnu/build/linux-boot.scm (boot-system): Rename the '--root' option to
'root'. Adjust doc.
* gnu/installer/parted.scm (installer-root-partition-path): Use 'root' instead
of '--root'.
* gnu/system.scm (bootable-kernel-arguments): Likewise.
(operating-system-boot-parameters): Adjust doc.
(operating-system-boot-parameters-file): Likewise.
* gnu/system/linux-initrd.scm (base-initrd): Likewise.
* doc/guix.texi: Adjust doc.
