The client then will, when trying to mount the NFS root, say: panic: nfs_mountroot: RTM_ADD: 51 >Fix: Workaround: Provide a 'bogus' gateway entry (I just added 'option routers 192.168.162.1', which worked). Possible fix: not try to add a route in the NFSROOT code if the gateway is not set, or ignore any errors and try to mount anyway. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
