Swap on 4.2 BSD

[Tim Evans]

I've recently inherited system-administration responsibility for 4 VAX 
11/750's running 4.2 BSD and have been rummaging around on them.  I've
discovered that, although /etc/rc starts up 'swapon -a' there is no
swap partition defined in /etc/fstab.

Our vendor is unable to locate any records on why this might have been
set up in this fashion.  Their response was that "BSD does paging so maybe
you don't need swapping" (!!!).

/etc/disktab's entry for the Eagle disk(s) on the 4 machines appears to
show a 'b' partition having been defined.

Question is:  lacking any records on why this system was set up in this
fashion, can I safely throw a line into /etc/fstab defining partition 'b'
as swap?  Thanks.
