CONFIG_UNIX98_PTY_COUNT and devfs

[Frédéric L. W. Meunier]

I used CONFIG_UNIX98_PTY_COUNT=32 and it created
/dev/pty/m[0-255]. Is there any way to make devfs only create
/dev/pty/m[0-31] ?

>From Configure.help:

"When not in use, each additional set of 256 PTYs occupy
approximately 8 KB of kernel memory on 32-bit architectures."

Does that mean it doesn't make any difference if I set
CONFIG_UNIX98_PTY_COUNT=1 or CONFIG_UNIX98_PTY_COUNT=256, and
ONFIG_UNIX98_PTY_COUNT=257 will create 512 entries ?
