Tips for GIT versioning Linux RAM Disk Image (ramdisk.gz) contents

Question

I've a Linux RAM DISK Image zipped in ramdisk.gz archive.

I modify the existing RAM disk image mounting it as a loop back device.

gunzip ramdisk.gz

mount -o loop ramdisk ramdisk_dir

vi xxxx

umount ramdisk_dir

gzip -9 ramdisk

I'd like to GIT version the content of the RAM disk image.

Any tips or recommendations to do it?
