Yes, it uses the labels. It should also be able to take options after the label, like
Code:
labelname option anotheroption

which would go into the kernel commandline options.

These options would be available via /proc/cmdline once the kernel boots, for you to use how you please in the initrd.

So you'd be customizing an initrd either way, really.

NAME
mkdumprd - (Re)build the initramfs for kdump SYNOPSIS
mkdumprd [-h] [-q] [-f] [-k kernelver] [-i opts] DESCRIPTION
mkdumprd (re-)builds the kdump initrd. For kdump, a special initrd is used because o the kdump initrd should include network modules and network configuration (and therefore is larger as the normal initrd used for booting), o the kdump initrd should use no splash screen, o the kdump initrd includes kdumptool(8) and all required libraries. This script calls mkinitrd(8) with all required parameters. If the initrd already exists, it checks first if the configuration file or the kernel are newer, and only rebuilds the initrd if necessary. OPTIONS
All option parsing is done via the getopt(3) function, and therefore follows all standard command line parsing rules. -h | --help Shows help output and exits. -k kernelversion Specifies the kernel version. If no version is specified and also no kernel or initrd are specified, then mkdumprd uses kdumptool(8) to find out the correct kernel and initrd. -K kernel Specifies the kernel binary. If you specify that option, also specify -I. -I initrd Specifies the resulting initrd. If you specify that option, also specify -K. -q Be quiet. Don't output status messages. Used to call mkdumprd(8) from /etc/init.d/kdump init script. -i parameters Append the specified parameters to mkinitrd(8) call. FILES
/etc/sysconfig/kdump Kdump configuration. See kdump(5). BUGS
