My suggestion:

of the installed RAM memory in the machine...
Your suggestion makes sense in principle. However, it is
/usr/share/initramfs-tools/init that performs the mount, so that's what
would need changing.
Ah, ok. Thanks Helmut!
As a workaround for your situation, I suggest adding a kernel parameter
initramfs.runsize=20M.
Yes, that should work.
Would you be able to provide a patch here? I think that if a runsize is
given, it should be honoured, so it would probably work like:
if test -z "$RUNSIZE"; then
if system_has_at_least_200mb_ram; then
RUNSIZE=10%
else
RUNSIZE=20M
fi

Yes, I'll try to send a patch.
I just wonder, what's the best way to get the amount of physical memory?
Something like this should work which gives size in kB:
mem_kb=$(grep MemTotal /proc/meminfo | (read txt mem txt2; echo $mem)) && echo $mem_kb
Is there a better way? I think glibc isn't running in initramfs, so "getconf _PHYS_PAGES" will probably not work?
