@ -9,6 +9,12 @@ nodes should be reliably created, but some rules and libudev will
not work correctly because the old kernels do not provide the expected
information or interfaces.
We are currently merging the Ubuntu rules in the udev default rules, and
get one step closer to provide a common Linux /dev setup regarding device
names, symlinks, and default device permissions. On udev startup, we now
expect the following groups to be resolvable to their ids by glibc's
getgrnam(): "disk cdrom floppy tape audio video lp tty kmem".
/dev/serial/by-{id,path}/ now contains links for ttyUSB devices,
which do not depend on the kernel device name. As usual, unique
devices - only a single one per product connected, or a real

- 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 kmem
Especially in LDAP setups, it is required, that getgrnam() is able to resolve
these group names while no network is available.
Operation:
Udev creates and removes device nodes in /dev/, based on events the kernel
