Subject: Manipulating udevdb attributes
Date: Mon, 06 Aug 2007 20:37:05 +0000 [thread overview]
Message-ID: <46B78671.5000807@cfl.rr.com> (raw)
Currently the udev rules while acting on an event for a device can look
at and modify environment variables associated with that device. The
admin can use udevinfo to query this information, but is there any way
to MODIFY it? If not, how hard would adding a tool be that can
arbitrarily modify values in the udevdb?
I ask because I am trying to fix the system to perform autodetection and
mounting on synthetic devices from device-mapper and md, but they need
to not mess with certain devices, such as snapshot devices, and other
internal devices. I was hoping to do this using a udevdb attribute that
can be set on devices that are meant for export, and only automount
devices marked as such.
