[SunRescue] Max capacity of harddisk supported by SS20

[CamielVanderhoevenCamiel.Vanderhoeven at asml.nl]

The way I see it, this is not a very good idea. The more you put in one
filesystem, the greater the risk that the file system gets corrupted. By keeping
all more or less frequently changing data on separate partitions (/home, /var,
/usr, /opt), your chances of being left with an inoperable system are somewhat
smaller. If you install a lot of free-/shareware software, keep your /usr
partition large. If you use a lot of commercial Sun software, keep your /opt
partition large.
