cleaning /dev

cleaning /dev

[mike dixon]

Hi - 

I just replaced devfs with udev.  I had/have something like1600 entries in /dev and would like to trim that way back to just what is needed (a home computer).  Can I boot from a floppy and remove /dev then restart and only the devs needed will be created?  If so, and it creates all1600 entries again (I don't know how much was left over from devfs), do I need to go through udev conf files figuring out how to keep so many from being created?

Mike

gentoo (uses devfs by default).  

I removed devfs entirely and was a little surprised to see udev re-using some of the goofball names of devfs by creating links.  I imagined gentoo's script was doing that but don't know enough about udev yet to know if some of these names are being used somewhere else (now).

it's because we cant use udev on 2.4.x ;)

udev comes with a devfs-compatible script

if you dont want /dev being populated with the standard dev files, 
edit /etc/conf.d/rc and set RC_DEVICE_TARBALL="no"

if that's not enough, read our udev guide:
http://www.gentoo.org/doc/en/udev-guide.xml

Thanks.  I used that option and now have only half the /dev files I had before (which is still 700+).  That's a start.

There's still piles of crap I don't think I need (like the stupid devfs hierarchical partition names) but will go through the links from the ptr you gave me to see if I can get it cleaned up the rest of the way.  

I'd read the gentoo guide before emerge'ing udev but took its advisement to keep gentoo's udev tweaks and therefore didn't read further  :-)
