I am personally happy as long as LKMs (such as > Arla's afs client, or OSS/FreeBSD) can be loaded and used. The truth is, they CAN be loaded and used PROVIDED you are using an a.out kernel. LKMs work using ld magic to relink the object file, the kernel, etc. and ioctl it on into the kernel, basically. It's strongly tied to a.out, and there's no reason at all to ever make LKMs ELFable, since KLDs already work, and work well for ELF and a.out, requiring no black magic of ld and /dev/lkm, just a simple int kldload(char *ko) syscall. LKMs die now, especially since 3.0.1 will by default (I'm pretty sure) have an ELF kernel. > > Kenneth Culver > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-current" in the body of the message > Brian Feldman _ __ ___ ___ ___ green@unixhelp.org _ __ ___ | _ ) __| \ http://www.freebsd.org/ _ __ ___ ____ | _ \__ \ |) | FreeBSD: The Power to Serve! _ __ ___ ____ _____ |___/___/___/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
