initrd: Use non-hyphenated kernel command-line parameter names.
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 '--load', '--repl', '--root' and '--system' to 'gnu.load', 'gnu.repl', 'root' and 'gnu.system', respectively. Adjust doc. (find-long-option): Adjust doc. * gnu/installer/parted.scm (installer-root-partition-path): Adjust accordingly. * gnu/system.scm (bootable-kernel-arguments): Add a VERSION argument and update doc. Use VERSION to conditionally return old style vs new style initrd arguments. (%boot-parameters-version): Increment to 1. (operating-system-boot-parameters): Adjust doc. (operating-system-boot-parameters-file): Likewise. * gnu/system/linux-initrd.scm (raw-initrd, base-initrd): Likewise. * doc/guix.texi: Adjust doc. * gnu/build/activation.scm (boot-time-system): Adjust accordingly. * gnu/build/hurd-boot.scm (boot-hurd-system): Likewise. * gnu/packages/commencement.scm (%final-inputs-riscv64): Adjust comment.
