Hammer & Screwdriver Perl script solution

Hi
I need to do this thing in awk (or perl?). I try to find out how can I identify 1st and 2nd result from the OR expression in gensub:

Code:
block='title Sata Mandriva
kernel /boot/vmlinuz
initrd /boot/initrd.img'
echo "$block" | awk '{ x=gensub(/(kernel|initrd) /,"\\1XXX","g"); print x }'

Generates this:
Code:
title Sata Mandriva
kernelXXX/boot/vmlinuz
initrdXXX/boot/initrd.img

Now I need to apply the change only on 1st found result:
Code:
title Sata Mandriva
kernelXXX/boot/vmlinuz
initrd /boot/initrd.img

Problem is that I don't know how to identify the 1st and second substitution.

Somebody help?

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
