Oh, well that makes more sense than using udev. I wasn't aware that -r would set the readahead value persistently in the LV metadata. That makes my life easy.
Thank you both.

Hey Peter,
Thanks for the response. I've previously tried the "change" action, and
adding the specifier for the DM_ACTIVATION environment variable had no
effect. I'm also aware of the capability to set the readahead on a
per-volume basis, but I'm looking for a solution which handles setting
these values at boot time and/or volume creation time.
Seeing you use star in the rules, looks like you want to change default when new LV is created: there is `readahead` setting in the lvm.conf file to do that.
