[andersen@slag andersen]$ dpkg -l modutils strace | tail -n2
ii modutils 2.3.9-3 Linux module utilities.
ii strace 4.2-4 A system call tracer.
I just downloaded the source to modutils-2.1.121,
modutils-2.2.2-pre8, and modutils-2.3.9 and every
one of them has:
open("/proc/modules", O_RDONLY)
in insmod/lsmod.c along with the comment
/* We've got no other option but to read /proc. */
I don't know where you got your strace, but I suspect it is broken. If it is
indeed working, I would dearly love to see the interface lsmod used to get the
kernel module information.
