    Hello.

    I have read some useful articles about the layout of the NetBSD
    filesystems. I specially like the next one, written by Grey Wolf:
    http://ezine.daemonnews.org/200209/diskpartnbsd.html

    Now, I have a question about mounting /var/run as a mfs filesystem
    (in the same way it is a tmpfs in Solaris). Let us suppose that
    a NetBSD machine has this fstab(5):

    /dev/wd0a / ffs rw,softdep 1 1
    /dev/wd0b none swap sw 0 0
    /dev/wd0e /stand ffs rw,softdep 1 2
    /dev/wd0f /var ffs rw,softdep 1 2
    /dev/wd0g /usr ffs rw,softdep 1 2
    /dev/wd0h /usr/contrib ffs rw,softdep 1 2
    /dev/wd0i /usr/obj ffs rw,softdep 1 2
    /dev/wd0j /usr/pkg ffs rw,softdep 1 2
    /dev/wd0k /usr/pkgsrc ffs rw,softdep 1 2
    /dev/wd0l /usr/src ffs rw,softdep 1 2
    /dev/wd0m /dump ffs rw,softdep 1 2
    /dev/wd0n /home ffs rw,softdep 1 2
    swap /var/run mfs rw,-s=1m 0 0 <- /var/run entry
    swap /tmp mfs rw,-s=16m 0 0
    kernfs /kern kernfs rw 0 0
    procfs /proc procfs rw 0 0

    With this configuration, we will have problems when shutting down
    the computer, that will not shut down cleanly.

    How can we set up a mfs filesystem for /var/run? From Grey Wolf's
    article, it looks possible. I like running /var/run as a memory
    filesystem, as in recent Solaris releases (well, it is a tmpfs
    in Solaris since Rel. 8).

    Thanks in advance for any help on this issue!

    Igor.
