what is the status of devfs?

[Robert P. J. Day]

   probably should send this to the main kernel list, but in playing
around, i noticed that DEVFS_FS is labelled as both OBSOLETE and NEW,
but in the Kconfig file, it depends on EXPERIMENTAL.

   it seems a bit inconsistent for anything to be simultaneously
EXPERIMENTAL, NEW and OBSOLETE, no?

I assume you are talking about 2.6.x :)
See Documentation/Changes line 115:
"DevFS has been obsoleted in favour of udev
(http://www.kernel.org/pub/linux/utils/kernel/hotplug/)"

Bye, Christian

I found the following in udev-FAQ:

Q: Why was devfs marked OBSOLETE if udev is not finished yet?
A: To quote Al Viro (Linux VFS kernel maintainer):
	- it was determined that the same thing could be done in userspace
	- devfs had been shoved into the tree in hope that its quality will
	  catch up
	- devfs was found to have fixable and unfixable bugs
	- the former had stayed around for many months with maintainer
	  claiming that everything works fine
	- the latter had stayed, period.
	- the devfs maintainer/author disappeared and stoped maintaining
	  the code.

oh, i knew devfs was on its way out, i was just curious about it being
labelled as EXPERIMENTAL, NEW and OBSOLETE all at the same time.

what's the story on proposed udev support some day?
