Yeah, this is because only in the rw case the whole image is copied into RAM,
and hence has additional memory requirements.
If the image is ro, it is used directly and hence doesn't need additional RAM.

I've checked the age of images.sh in my private agama project and it is March
4th 2023.
So, this is older than the commit to the dracut git:
https://github.com/dracutdevs/dracut/commit/52351cfa049a9594d539e6a5337d591e8039ab80

AFAICR, I've used that injection of the memory check via images.sh during my
testphase for this commit.
Not sure how it went into the official agama sources but it should be obsolete
now.
