If the devfsd.conf file contains a line with a CFUNCTION (or presumably
MFUNCTION) event and the path is set to GLOBAL, then devfsd segfaults. As
CFUNCTION GLOBAL symlink $devname mouse
CFUNCTION GLOBAL unlink mouse
One or both of those lines (I've tested each one alone) fails. However,
changing the action fixes the problem and changing "GLOBAL" to
"/lib/libc.so.6" fixes the problem as well.
I do not know if this is a defsd/kernel error or a redhat error, and I
apologize for not trying to find out, but I assume you guys are better
equipped to make that decision.
BTW, I'm using devfsd-2.4.0-0.43.4 with a custom kernel from the rawhide
sources of the same version.
