if the thing starts to upgrade and does "ttinstall core dump" or
something like that, check for packages with pkginfo files that
lack a BASEDIR= entry. that causes those core dumps. look for
them before you start -- forewarned is forearmed. just use / as the
base dir entry.
and you'll have to be careful about the handling of the SSA. upgrading
the firmware has to be done in the right order, and it used to be if
the firwware upgrade failed it erased what was there, and wouldn't proceed.
so you couldn't go back, and you couldn't re-try. if you have to do it,
it may affect the order of things, but you'd have to do it whether you
were installing or upgrading.
tradeoffs: the upgrade takes longer to execute, but less time to prepare.
the install is faster (in terms of how long the CD is spinning) but
you have to do much more preparation.
and, of course, you realize i'm not covering everything.
everything. i'm not kidding.Quote:>If I choose to install from scratch, what must I take into account? How
