New version. From RELEASE-NOTES:
udev 112
========
Bugfixes.
Control characters in filesystem label strings are no longer silenty
removed, but hex-encoded, to be able to uniquely identify the device
by its symlink in /dev/disk/by-label/.
If libvolume_id is used by mount(8), LABEL= will work as expected,
if slashes or other characters are used in the label string.
To test the existence of a file, TEST=="<file>" and TEST!="<file>"
can be specified now. The TEST key accepts an optional mode mask
TEST{0100}=="<is executable file>".
Scsi_id now supports a mode without expecting scsi-specific sysfs
entries to allow the extraction of cciss-device persistent properties.
