MFS will not cause you problems. It's safe to leave it in. FDESC has had problems in the past with panics. I had a patch for 2.x & 3.x that added support for pipes which fixed the panics. 4.x now has support for pipes so the exploit to panic an unpatched FreeBSD no longer works, though there might be something else in FDESC that might cause the panic. IIRC, find /mnt | xargs ls -l would cause a panic of FDESC. Under 4.0 the following output is produced: [snip] ?--------- 0 root wheel 0 Oct 3 06:50 0 [snip] Adding the following to DTYPE_PIPE handling in fdesc_vnops.c might fix this too: if (fp->f_type == DTYPE_SOCKET) vap->va_type = VSOCK; /* XXX pipe? */ else vap->va_type = VFIFO; Regards, Phone: (250)387-8437 Cy Schubert Fax: (250)387-5766 Team Leader, Sun/DEC Team Internet: Cy.Schubert@osg.gov.bc.ca Open Systems Group, ITSD, ISTA Province of BC To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
