如何恢复/dev/*的文件属性以及安装devfs的方法

ultralix

不小心
/dev#chmod 660 *
了

我该怎么把所有的设备恢复到该有的权限？

试试 /sbin/MAKEDEV 能不能解决，先看看man

如果用的是devfsd那么重新启动devfsd就行了吧。

怎样快速过渡到devfs？
以前我是看IBM那个教程搞的，要改 /sbin/init 的，现在呢？

Basic installation
------------------
apt-get install devfsd
Get latest 2.4 kernel
Recompile kernel with
    devfs support enabled
    devfs mount on boot enabled
    devpts disabled
    Character device: ACP modem support enabled (CONFIG_MWAVE=m)
Install kernel and modules and update grub menu, etc.
Remove "/dev/pts" line from /etc/fstab
    (/dev/pts files are created by devfs)
Make backup of /dev directory by doing
        cd /dev ; tar cvf ~/mydevdirectory.tar *

X
-
Edit /etc/X11/XF86Config-4 to change '/dev/psaux' to '/dev/misc/psaux'
as the source of PS/2 mouse data

Sound
-----
Edit /etc/alsa/modutils/1.0 so that snd-pcm-oss is loaded above snd-card-cs4236
Run update-modules
    (This is necessary because I am using ALSA 0.9 and esound only supports ALSA 0.5
     native devices at present; so I have to use esound with ALSA 0.9's OSS-emulation
     devices: /dev/dsp et al.  For some reason, after moving to devfs the *-oss
     modules don't get loaded automatically by the module loader.)
