During boot I have messages about /etc/udev/rules.d/70-nut-usbups.rules doing SYSFS calls. Because is coming udev changes, we now have a warning about this. When udev will switch, it will become an error. Other scripts in /etc/udev/rules.d/ are fine: 55-usbirboy.rules 64-md-raid.rules 70-bluetooth-pcmcia.rules 70-libgphoto2.rules 70-persistent-cd.rules 90-hal.rules xen-backend.rules 64-device-mapper.rules 65-mtp.rules 70-bluetooth.rules 70-nut-usbups.rules 70-persistent-net.rules 99-fuse.rules xend.rules Please update Nut. Sorry for being vague, but as it's an early boot message, it's hard to catch, and copy.
Luckily, the message is in var: Mar 16 16:10:42 uranus udevd[2027]: SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent device, in /etc/udev/rules.d/70-nut-usbups.rules:10 Mar 16 16:10:42 uranus udevd[2027]: SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent device, in /etc/udev/rules.d/70-nut-usbups.rules:14 Mar 16 16:10:42 uranus udevd[2027]: SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent device, in /etc/udev/rules.d/70-nut-usbups.rules:18 [...] Mar 16 16:10:42 uranus udevd[2027]: SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent device, in /etc/udev/rules.d/70-nut-usbups.rules:88 Mar 16 16:10:42 uranus udevd[2027]: SYSFS{}= will be removed in a future udev version, please use ATTR{}= to match the event device, or ATTRS{}= to match a parent device, in /etc/udev/rules.d/70-nut-usbups.rules:90
The best way to handle this bug is to bump the version of nut to 2.4.3. It been released for about 4 weeks ago. That version include a new rules file. Then it is best to depricate the versions <= 2.4.1 as it is not supported upstream.
2.4.3 with a fix now in CVS.
I could not read all messages in first place; now I see an other one (hand copy) BUS= will be removed in a future udev version, please use SUBSYSTEM= to match the event device, or SUBSYSTEMS= to match parent device, in /etc/udev/rules.d/70-nut-usbups.rules:6
