recommend to replace a distro's udev installation with the upstream version.
Requirements:
- - Version 2.6.19 of the Linux kernel for reliable operation of this release of
- udev. The kernel may have a requirement on udev too, see Documentation/Changes
- in the kernel source tree for the actual dependency.
+ - Version 2.6.22 of the Linux kernel for reliable operation of this release of
+ udev. The kernel must not use the CONFIG_SYSFS_DEPRECATED* option.
- The kernel must have sysfs, unix domain sockets and networking enabled.
- (unix domain sockets (CONFIG_UNIX) as a loadable kernel module may work,
- but it does not make any sense - don't complain if anything goes wrong.)
+ Unix domain sockets (CONFIG_UNIX) as a loadable kernel module is not
+ supported.
- The proc filesystem must be mounted on /proc/, the sysfs filesystem must
be mounted at /sys/. No other locations are supported by udev.
+ - The system must have the following group names resolvable at udev startup:
+ disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, kmem.
+ Especially in LDAP setups, it is required, that getgrnam() is able to resolve
+ these group names with only the rootfs mounted, and while no network is
+ available.
Operation:
Udev creates and removes device nodes in /dev/, based on events the kernel
