autostart bug

[Basil Fernie]

Hi Nio,

Thanks for the prompt response. I checked out the linked threads and my  
conclusion is that most of the advice offered actually addresses the  
converse of my problem. There are solutions to the question "How do I  
introduce a new application package offline to an existing installed  
distro. I read them with interest, this is also a problem I sometimes  
face, but what is really on my mind is this:

How do I overwrite an existing full working installation's system files,  
including the Linux kernel, with an upgrade to a more recent version (from  
12.04 to 14.04 in this instance)? Specifically, I have the entirety of the  
new version as released in an iso on a bootable DVD already; I have run  
that iso live from the DVD and am satisfied that it's fine, apart perhaps  
for a few regular-type dsriable updates which I will anyway do via  
Lubuntu's Update Manager in due course.

What I would love to be able to do is boot from the new DVD and invoke the  
live installer, selecting then the (currently non-existent) option to  
overwrite the existing system including kernel, system executables,  
scripts, configuration files, and distro-standard included application  
packages that are more recent than ones I have already installed over the  
older distro, without being forced to reformat the entire Lubuntu  
partition, thereby losing all my painfully selected, downloaded and  
installed additional application packages not to mention the gigabytes of  
user data.

To preserve these important to me things I am currently forced to backup  
everything that I think will be endangered, do a clean install of the new  
Lubuntu, then restore everything from backup, in the process probably  
overwriting some important new files that were installed with the new  
version of the distro. A job stretching over probably 2 or 3 days  
initially, followed unpleasant random discoveries at various (critical?)  
points.

The only remotely relevant suggestion I could find would mean doing a  
clean  live install of e.g. Lubuntu 14.o4 on another machine booted from  
the new DVD, then copy them into the named special directory on my  
operational laptop's operational partition, then do a "no-download"  
installation from that directory. I expect that will avoid the feared  
non-optional reformatting requirement of the target partition, since the  
named directory is on that partition?

The obvious potential problem here is that the interim machine on which  
the clean install is done, may have subtle differences at the hardware or  
BIOS level and thus force a clean installation that might be somewhat  
inappropriate for the eventual operational machine.

Variations on this theme which might be better would include setting aside  
a bootable partition on the operational target machine for the interim  
clean install, then doing the copy at HDU speeds into the named directory  
in the target operational partition, alternatively (and better for  
propagation across a small family of computers needing the same upgrade)  
doing the interim clean installation onto a bootable memory stick mounted  
in the operational target machine, then copying back as before.

Any comments?

Best regards to all,

Basil
