Skip to Bottom line: Does devfs do devpts on 2.6? Didn't for me.

I'm using devfs on 2.6.0-test11. I have never run into the impossible to fix problems. I run devfs with very little old compatible naming. I edited /etc/devfs/compat_symlinks to give me /dev/sd* /dev/hd* and weirdly ln -s /dev/dsp2 /dev/dsp since all sound apps only seem to look for /dev/dsp which is only a dummy with nforce2.
In 2.6 devfs would not do devpts for X so I put devpts back in the kernel and instantly got on with my work. I'm not sure if that means devfs can't do devpts in 2.6. I don't care.
I see no devfs devices for a 32-bit cardbus pcmcia controller pci card which is id'd by yenta and cardmgr(pcmcia-cs v3.2.5), so I am switching to sysfs udev hotplug to see if that helps. Actually I can mount sysfs to /sys now and look around first but proc and var agree there is nada but there are two cards in slots.
In the cdrecord thread Linus said some things about target/bus/lun naming and I must admit that it is nice to get back where ls /dev shows what drives there are without having to tree out into /dev/scsi/host/bus/target/lun/* to see how drives are recognized. That can be improved in most configurations by using compat symlinks instructions for /dev/sd* in /etc/devfs/compat_symlinks but as Linus explained iscsi handled better by sysfs udev /dev/s?? and not 0,0,0 targbuslun cdrecord-style.
I like devfs and haven't ever had an error burning cd's with ide-scsi but I'm switching to udev and ide-cd to suck up to Linus before I start plaguing him about my pcmcia controller and yenta not working together--udev might work better with hotplug than devfs so I should try that first.
It seems dubious that Gooch isn't maintaining devfs and syfs could be moving away from compatibility with devfs, and there are proven impossibilities about the devfs way. Devfs is a lot less broken than windows, though. Devfs might be good enough to Walmart-Microsoft pretty good alright rip the guts out of userland, but that's not good enough for the os that runs the internet.
