On   5 Jun, this message from Benjamin Herrenschmidt echoed through

Na. I run devfs on my Powerbook, and I am very happy. Never had any
problem. I am absolutely certain (even if it may not be true :-) that
using devfs saves me quite a number of HD spinups.

Mine show this:

mlan at pooh:~$ ll /dev/apm_bios  /dev/misc/apm_bios
lr-xr-xr-x    1 root     root           13 2003-05-14 22:42 /dev/apm_bios -> misc/apm_bios
crw-rw----    1 root     root      10, 134 1970-01-01 01:00 /dev/misc/apm_bios

This is with the Debian devfs package, which _may_ fix up a few things.
My devfs config says this:

mlan at pooh:/etc/devfs$ find . -type f |xargs grep apm
/conf.d/apm:REGISTER ^misc/apm_bios$   PERMISSIONS root.root 0660
/conf.d/pmud:REGISTER ^misc/apm_bios$   PERMISSIONS root.root 0660
/perms:REGISTER ^misc/apm_bios         PERMISSIONS root.root   0660

plus this one for setting up symlinks:

mlan at pooh:/etc/devfs$ head compat_symlinks
# Enable full compatibility mode for old device names. You may comment these
# out if you don't use the old device names. Make sure you know what you're
# doing!
REGISTER        .*              MKOLDCOMPAT
UNREGISTER      .*              RMOLDCOMPAT

I'm tempted to say: install Debian :-)
