With very deeply nested devices, We can not use a single file name to carry an entire DEVPATH. Use <subsystem>:<sysname> as the database filename, which should also simplify the handling of devices moving around, as these values will not change but still be unique. For the name stack we use the <maj>:<min> now as the filename. > On Tue, Aug 18, 2009 at 09:59:56AM -0400, Ric Wheeler wrote: > The first is that udev grumbles during boot about "file name too long" > like the following: > > Aug 17 06:49:58 megadeth udevd-event[20447]: unable to create db file > '/dev/.udev/db/\x2fdevices\x2fpci0000:00\x2f0000:00:04.0\x2f0000:17:00.0\x2f0000:18:0a.0\x2f0000:1f:00.0\x2fhost11\x2fport-11:0\x2fexpander-11:0\x2fport-11:0:0\x2fexpander-11:1\x2fport-11:1:0\x2fexpander-11:2\x2fport-11:2:17\x2fexpander-11:3\x2fport-11:3:1\x2fend_device-11:3:1\x2fbsg\x2fend_device-11:3:1': > File name too long

o drop support for node names in name stack, support only symlinks
|
|
With well defined and kernel-supplied node names, we no longer need
|
|
to support a possible stack of conflicting symlinks and node names.
|
|
From there on, only symlinks with identical names can be claimed
|
|
by multiple devices. It will simplify the logic a lot and shrink
|
|
/dev/.udev/names/ significantly. Also exclude "*/MAJ:MIN" link names
|
|
from the name stack, they can not conflict.
|
|
o remove most NAME= rules (they are provided by the 2.6.31 kernel)
|
|
o get rid of braindead "scan all devices to find myself" libusb interface
|
|
if it can not be fixed, drop libusb entirely
|
|
o convert firmware.sh to C
|
|
|
|
o symlink names to udevadm will no longer be resolved to old command names
|
|
o "udevadm control" commands will only accept the --<command> syntax
|
|
o drop all support for the DEPRECATED sysfs layout
|
|
o add warning for BUS, SYSFS, ID
