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
