[OT] devfs is obsolete, but dbus/hald/ivman does not spend more resources at boot time?

[Gustavo Guillermo Pérez]

I was used to mount devfs in a separate folder, to search for a ZISO file on 
hard drives or DVD/CD units in my boot ram rescue disks, and Gentoo live DVD, 
in last kernel versions devfs still there but not anymore in config, we still 
able to use it, touching some files.

Just to know ¿How many releases will still there?

How do you a search for drives with hald/dbus at boot time on a ramdisk it is 
not more complex?!?!?!.

Well, I still wanting for a while devfs, untill I use to use hald/dbus :(

devfs has been fully removed from the kernel for 2.6.18, but had been
disabled and really not working at all since 2.6.13, which has been for
a year now.

What exactly are you trying to do?  Look at /sys/block/ for all block
devices in the system.  If you want to do it in a more portable and
cross-OS way, use HAL, and ask those developers on how to do it.

True, but for hard drives and CD units works fine

Yes there are the block devices and partitions but I'm not sure if removable=1 
means CDROM...

I guess, ok, I'll give a try to hal, and I see I can use too 
the /sys/block/*/dev info to make nodes, and would be the same, cause is just 
for probing media and looking for a big file with the system, when the system 
is found, dbus/hal/ivman take scene.
