Description of problem:
I frequently find myself having to run mkinitrd from the Fedora rescue disc in order to port an existing Fedora installation over to new hardware.

I type "mkinitrd -f /boot/i" and then the TAB key, then maybe one digit and TAB again, so now I have "mkinitrd -f /boot/initrd-2.6.26.3-29.fc9.x86_64.img".  So far so good.

But now mkinitrd requires me to type out "2.6.26.3-29.fc9.x86_64" using my fingers (no cut-and-paste in rescue mode).  This seems somewhat redundant to me, not to mention error-prone.

It would save a lot of time if initrd, seeing that the image file is called "initrd-XYZ.img", would look for kernel version XYZ if I didn't specify one explicitly.  Of course if the image file isn't called that then mkinitrd would still require an explicit kernel version.
