Of course many people never upgrade their ram, and often going beyond 50%
of maximum gets very expensive.
Also many people never suspend.
Also dmidecode is x86 only and some older systems didn't have it, so it
wouldn't help the majority of architectures.
So while it is an idea, I am not convinced it doesn't actually create
problems.
Besides I could move the disk to a new system later which could have
even more ram, so even making it as large as dmidecode says won't solve
all cases. I would think that case is at least as likely as maxing out
the ram in a machine is.
