Yes, but I'm the first to admit that's the wrong lines.
The reasons we didn't choose that for module signatures:
1) I was unaware of it,
2) We didn't have a file descriptor in the module syscall, and
3) It needs attributes, and we don't understand xattrs in cpio (though
bsdcpio does).
#1 and #2 are no longer true; #3 is a simple matter of coding.
Since signing binaries is the New Hotness, I'd prefer not to keep
reiterating this discussion every month. Let's beef up IMA instead...
Thanks,
Rusty.
