vsta fs FAQ entry

I've been trying to get a working vfs fs.
I spent much of today reading fs & wd code;
on a whim I mounted wd in the root fs and lo
and behold, it had entries in it! And they
were different than the one in the sample inittab line...
that simplified things lots.

Here's a possible FAQ entry for the next poor fool
who tries this:

Q: How do I make a vstafs filesystem?

A: For DOS 6.2, there are two possible partitions on a disk:
the main one, and a secondary one. It is possible to create
logical partitions in the secondary partition to subdivide that
partition even further. To see what partitions you have available,
add a line of the form:
disk/wd /wd
to the /vsta/etc/fstab file and reboot, or use the command
$ mount disk/wd /wd
to accomplish the same effect temporarily. Look in the
/wd directory for the names of available partitions.
Supposing you wish to use the partition wd0_dos1, use the command
$ stat /wd/wd0_dos1
to find the exact size of the partition. Divide that number by
512 to get the number of sectors, then the command
$ mkfs_vfs /wd/wd0_dos1 number_of_sectors
will initialize a vstafs file system on that partition.
Now you can run the filesystem server:
$ /vsta/boot/vstafs /wd/wd0_dos1 fs/vfs
Finally, you must map the namer pathname fs/vfs into the
root heirarchy with a mount command:
$ mount fs/vfs /vfs
If you want the filesystem mounted at boot time, find the
vstafs command in the /vsta/etc/inittab and correct it to
your device name (note the different syntax when portnames
are used); uncomment or introduce the necessary mount
line in the /vsta/etc/fstab file.
