Stupid question time:
A great deal of text has been expended over the years by people desperately
trying to make sure you didn't need /proc mounted to have a usable system,
for some definition of usable. Now with rootfs, initramfs, sysfs, and the
libfs inspired "make a filesystem rather than an ioctl" policy, the main
argument against requiring the use of /proc is that it has a lot more gunk in
it (left over from the days when it was the only ramfs type system to export
values in) than anyone is comfortable with. (The argument against /dev/pty
largely seems to be inertia, now that the "number of ptys" issue as a config
tunable seems to have been cleared up).
There seems to be some sort of nebulous plan for eventually stripping down
/proc, perhaps making a "crapfs" that's a union mount on top of /proc
providing deprecated legacy support for a release or two. But I haven't
heard it explicitly stated.
So my questions are:
1) will some subset of /proc, /sys, /dev/pty, etc become required at some
point in the future on everything but the most customized embedded systems?
Or is keeping the system usable without them still a goal?
2) Is there a plan to rehabilitate /proc?
(I ask because I don't know. Maybe I missed some important posts...)
