Because proc does it right and all others wrong, for historical reasons.

Having the pseudo FSes in fstab has advantages:

1) Easy to see what gets mounted where
2) Easy to adjust the options
3) Easy to mount when booting with init=/bin/sh is required to fix
   breakage. E.g. when fixing my raid having /proc/mdstat comes in
   handy.

The initscript already support having the filesystems in /etc/fstab. It
just doesn't have them there by default. Instead it uses hard to find
and partially undocumented variables from multiple files to do some
magic.


I would like to have the filesystems added to /etc/fstab at least as
comments so it is easy for users to uncomment them to e.g. change the
size of the tmpfs without first having to search through the boot
scripts to find out how the filesystem magically gets mounted and where
the size variables come from.
