Package: udev
Version: 0.125-6
Severity: minor
Hi,
Udev manual says:
ATTRS{filename}
(...) Trailing
whitespace in the attribute values is ignored, if the specified
match value does not contain
trailing whitespace itself.
I applied each of five rules for sda1 by:
- uncommenting exactly one specified and commenting four else (udev
does not processed more than one rule for sda1, see
http://www.linuxquestions.org/questions/linux-hardware-18/why-udev-ignores-multiple-rules-for-the-same-device-672179/)
in rule file in /etc/udev/rules.d,
- udevadm control --reload_rules; udevadm test --force /block/sda/sda1
| grep -E 'add symlink'
Below there are results. Trailing whitespace was ignored only between closing
double qoute and comma.
# e: empty, q: quote, s: space
KERNEL=="sda1", \
NAME="%k", \
ATTRS{serial}=="0000000272",\
SYMLINK+="pendr-eqe"
# udevtest monitor: udev_rules_get_name: add symlink 'pendr-eqe'
KERNEL=="sda1", \
NAME="%k", \
ATTRS{serial}=="0000000272" ,\
SYMLINK+="pendr-eqs"
# udevtest monitor: udev_rules_get_name: add symlink 'pendr-eqs'
KERNEL=="sda1", \
NAME="%k", \
ATTRS{serial}=="0000000272 ",\
SYMLINK+="pendr-sqe"
# nothing about pendr-sqe from udevtest monitor
KERNEL=="sda1", \
NAME="%k", \
ATTRS{serial}==0000000272,\
SYMLINK+="pendr-eee"
# nothing about pendr-eee from udevtest monitor
KERNEL=="sda1", \
NAME="%k", \
ATTRS{serial}==0000000272 ,\
SYMLINK+="pendr-ees"
# nothing about pendr-ees from udevtest monitor
Why pendr-sqe has not created?
Preventively, I append info about sda1:
# udevadm info --attribute-walk --name=sda1
Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
