Upgrade Trail

Hi Bill,

I agree with the others here, upgrades are not good.

1) They are amazingly slow - my last attempt was over 24 hours!
2) After this long wait something has gone wrong.

But I can do a rebuild in 2-3 hours including backup and restore of data.
And it's largely unattended.

As someone else suggested, I keep a second disk, actually in the same
cabinet, and I do regular backups to it so that I can anyway restore easily
whatever happens.

I also have an install script (./install.sh). Part of which is shown in my
PS.  The full script is quite long, like 4 pages to print out.

But the whole thing is quite painless.



PS - ./install.sh


# Update sources for ubuntu apt repository to main repository.  Some local
respositories don't have everything
# (eg using kpackagekit, set server to 'main'
# Whie you're doing this manually intensive stuff, also configure cpan and
set prepend requirements to yes.
# I have backed up the ubunto apt repsitory to a stored file.  Thes two
lines take a backup and restore from stored version.
# cp /etc/apt/sources.list /etc/apt/sources.list.backup
# cp
rces.list /etc/apt/sources.list
