I have core and kernel files. System had only the one partition with softupdates enabled. I am using both MFS and devfs for other partitions, just FYI: /dev/sd0s2a on / (local, writes: sync 27 async 78)) devfs on dummy_mount (local) mfs:21 on /tmp (asynchronous, local, writes: sync 28 async 61)) /dev/sd0s2e on /var (local, writes: sync 224 async 265)) /dev/sd0s2f on /usr (local, writes: sync 8 async 196)) /dev/sd0s2g on /a (local, writes: sync 497 async 1789)) devfs on /dev (local) procfs on /proc (local) Here is kernel config, for grins: # # GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks # # For more information read the handbook part System Administration -> # Configuring the FreeBSD Kernel -> The Configuration File. # The handbook is available in /usr/share/doc/handbook or online as # latest version from the FreeBSD World Wide Web server # <URL:http://www.FreeBSD.ORG/>; # # An exhaustive list of options and more detailed explanations of the # device lines is present in the ./LINT configuration file.
