Package: udev
Version: 175-3.1
Severity: wishlist

Dear Maintainer,

Since kernel 2.6.37, some infos are available in /sys for associated loop
devices, especially the backing file.
I have written a rules file:

========== /etc/udev/rules.d/60-loopback.rules =============

SUBSYSTEM!="block", GOTO="loopback_end"
KERNEL=="loop?*", OPTIONS+="watch"

ACTION=="add|change", \
        KERNEL=="loop?*", \
        TEST=="%S/block/%k/loop/backing_file", \
        PROGRAM=="/bin/cat %S/block/%k/loop/backing_file", \
        ENV{BACKING_FILE}="%c"

LABEL="loopback_end"

============================================

Works fine

Is it possible to add a similar file in the udev package (but maybe this is a
task for 'util-linux') or to modify an
existing file (maybe 60-persistent-storage.rules) ?

Thanks
