[SunRescue] Max capacity of harddisk supported by SS20

Thu Jul 20 13:01:01 CDT 2000

This one's my admin workstation so I've just been installing things wherever
they get put by the pkgadd or make install.  I know that's not a good idea
in the long run but this is really a system I expect to reconfigure several
times as I learn more. (Whew!  It's amazing what I've learned in the 6 - 8
months I've been a Solaris admin.)

Anyway as I keep learning more I find that I have to re-load the system
occasionally due to mistakes I made previously or things I now know that
would make the system more efficient.

I kind of see it all as a learning experience that earns me money. ;-)

Sincerely,

Mike Hebel

Partitioning depends alot on what you intend to use the system for.
Usually it's a good idea to keep the root file system as uncluttered as
possible.  (/home Should Not be on it)  I usually leave /etc on /, and
just about everything else gets it's own partition.  Again, it really
depends on what it is being used for.  (I don't install much on /opt, so
it gets left on / once in a while)
