After searching the boards, I dug through the udev man pages and rule files looking for a way to modify the default automount options for USB flash drives. Apparently, the options are somewhere else. Is there a simple way to add noatime to the default mount options? Currently, the flash drive is automounted as follows:
/dev/sdb1 on /media/F12B-X86_64 type vfat (rw,nosuid,nodev,uhelper=devkit,uid=500,gid=500,sh ortname=lower,dmask=0077,utf8=1,flush)
I'm using Fedora 12, beta RC 2 in case that makes a difference.
