Or, even better, look at the difference between installed physical RAM
and how much RAM is available to userland processes.

We have a good starting point. We can look at the code/data/bss from

Linux is known to _work_ on SOHO MIPS boxes, with 4MiB of flash and
16MiB of RAM. Y
You have to look at the in-memory sizes, not the on-disk sizes.
Linux kernels are very barebones when it comes to what is compiled directly
into the kernel image on disk. Everything else is loaded from modules at
boot time. Especially if using distro-provided kernels. They even use ram

And yes FreeBSD kernel is huge. doesn't really matter with 1GB or more RAM
but yes - it is huge even relative to linux.
Ah, any insight as to why?
my custom compiled kernel:
-r-xr-xr-x 1 root wheel 8791402 6 kwi 22:08 /boot//kernel/kernel
only with features i need. linux is AFAIK like 3-4

Well, it's relatively easy to experience what it's like.
Reboot your machine with 32mb. Try to do things like bring up network
interfaces. Snark when stupid stuff occurs, like you can't allocate
enough mbufs for the driver RX path _and_ run the ifconfig command to
completion to bring said interfac
