Nobody's talking about axing, I was just surprised to see that the only reference to the LIBMCHAIN which enables the file was from NOTES. If it is used by nwfs and smbfs, shouldn't files contain these lines ? kern/subr_mchain.c optional smbfs kern/subr_mchain.c optional nwfs -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
