fsck to RAM?

Does anyone know what the obstacles are to putting fsck for common 
filesystems into RAM before the rest of fstab is mounted?

I'm dealing with a number of older persons dipping their toes into 
Linux, and whenever there is a power event, they all get the dreaded 
root prompt requesting an fsck on their mounted root partition.  
Everything on the internet points to booting from a live cd/usb, and 
fsck-ing it from there, but that is kinda terrible.  If it were in the 
initramfs, then they could unmount root & do the fsck without having to 
reach for a livecd.
