Devices in group disk read-only?

[Matthew Saltzman]

Since installing FC4, /dev/hda* has group disk and group permissions 
"r--".  This breaks raw disk access in VMware.  Changing group permission 
to "rw-" solves that problem, but the change is not preserved across 
boots.

Just recently, /dev/st0* has also become "r--" (also in group disk).  I 
don't recall exactly what package I installed about a week ago that might 
have affected this.  Before last week, amanda worked fine.  But since 
then, amdump complains that my tape is not writable.  Changing group 
permissions on /dev/st0* to "rw-" solves this issue, but the change is not 
preserved across reboots.

It looks like this is set in /etc/udev/rules.d/50-udev.rules, but udev 
hasn't been updated recently.  What package affected these permissions for 
my tapes?  What's the best way to fix them permanently?

TIA.
