[ASK] clarify some concerns regarding filesystems

Hello,

I look at my /etc/filesystems and see these stanzas

Code:

/SUM:
        dev             = /dev/lv_sum
        vfs             = jfs2
        log             = /dev/loglv00
        mount           = true
        options         = rw
        account         = false

/var:
        dev             = /dev/hd9var
        vfs             = jfs2
        log             = /dev/hd8
        mount           = automatic
        check           = false
        type            = bootfs
        vol             = /var
        free            = false
        quota           = no

As I know, mount = true means the mountpoint will be mounted at boot time, and false mean opposite to true. But what is the meaning of automatic here? The same with true?

Assuming I have created a new volume and mount it manually to somewhere. If I want to add it to /etc/filesystem, which log I will specify like below

Code:

/dev/loglv00

is it mandatory for all the volumes? In case the NFS do we need this?

As observed in my environment, the NFS is added to /etc/filesystems without log volume.
