[SunRescue] Max capacity of harddisk supported by SS20

[MikeHebeldruaga at pmail.net]

Mostly so I don't have to worry about space restrictions for /var /usr /opt
etc.

(Besides, kind of a moot point now - I partitioned the drive, just to be
safe, at 1.5G for / and the rest (- swap) as /opt.  It's restoring from tape
now.)

Is there something wrong with this or is this just "not a good idea"?

Sincerely,

Mike Hebel

Why would you want a root partition of 4 GB???
