Robert P. J. Day (rpjday(a)mindspring.com) said:
based on my reading, the new kernel prefers to read from the
file /etc/modprobe.conf, rather than the older /etc/modules.conf.
to help in the migration, there is the utility
"generate-modprobe.conf", but in this situation, it doesn't work --
it fails complaining of a missing "modprobe.old".
A new modprobe.conf should be generated on the first upgrade to
2.6 capable modutils, with the contents of whatever's in
modules.conf at the time. Changes aren't kept in sync
back and forth, however.
