Actually, as far as I'm aware, the 4K would be page-aligned by
default due to our malloc(3) implementation.
Wasn't there just a recent discussion about running 1.x binaries?
1.x binaries wouldn't notice and wouldn't be able to tell
if BUFSIZ is different in 10.x
I wasn't concerned about those specifically- I was just using this as an
example of leaving stuff alone.
If you're going to talk about making a change to defaults, the default
MAXPHYS and DLFTPHYS have been undersized for years now.
Indeed, but as I understand it, those require device driver changes ?
Ah, well 10.X would be an ideal time to find out!
