That udev and kernel match each other. But you are right, rest of=20
userspace that uses udev might not necessarily match.

And there is another issue: AFAIK distributors handle at least parts of=20
the udev configuration including rules.

Well other solution would be to guarentee that SYSFS_DEPRECATED works=20
correctly in udev until it will be deprecated and remove in kernel source.=

But then you suggest it the other way around:

I am running a mixture of Debian testing/unstable/experimental.

martin@shambhala:~> apt-show-versions | grep udev

libudev0/squeeze uptodate 146-5
udev/squeeze uptodate 146-5

Anyway, I disabled CONFIG_SYSFS_DEPRECATED now.

Maybe its more about the discoverability of such issue: I don't look into=20
the boot log / syslog every day. ;)

Hopefully upward incompatible changes in SysFS could be avoided in the=20
future.

Ciao,
