# of pty entries under /dev

System configuration: Linux  2.4.18 + devfsd v1.3.25 
 
I saw the following links /dev/ptya(0-f), /dev/ptyb(0-f) etc pointing to
/dev/pty/m0--m255.
Since I don't need that many ptys, try to shrink down the entries under
/dev. but changing kernel configurations CONFIG_UNIX98_PTY_COUNT from
default 256 to 10 does not change the number of  /dev pty entries, it still
has 256 of them.
CONFIG_DEVPTS_FS is not enabled ( devfs readme indicates some problem of
having both devpts and devfs enabled, so I just disabled devpts). Even
enabling CONFIG_DEVPTS_FS did not make a difference in this case.

Any hint?
