I have been thinking tha it would be neat to have as it were, one
install of LiBO and have it "updated" in all the same directories all
the time, even if it were a new version of LiBO that was being
"installed - updated", unless the User specifically elected to have
multiple installations of different versions, making the default that
there is only ever one main copy that is updated all the time.

Not sure where thinking is on this for LiBO at the moment, but is it
concievable that updating even to each new version could, after a User
response, be automatic and if elected by the User - replace the
previous version automatically please?

Hi Paul,

A first step would be to replicate the update notification feature
available in the OpenOffice.org. I guess only infrastructure is missing
for that one.

I remember last year in Orvieto there were some talks about new
packaging for all platforms that would allow online installation
(allowing user to select, download and install any combination of
languages, cutting space requirements to do full install sets).

I do not know what is the current status of this development and if it
would be easier to add autoupdate feature after that task is completed.

Kind regards,
Goran Rakic

Paul,
I do agree with the principles of your suggestion. Certainly on Windows installs this is true as evidenced by the "Install Folder" left on the desktop. And leaving the install folders around, not cleaning up after the install, or an uninstall not removing everything that was installed seems rather unprofessional. So, yes, I concur. However, I believe that may be only for Windows...

*nix(Linux|Unix) installs can use a variety of install/package management programs (e.g. apt, yum, rpm, et al.) that resolve this issue. And these package management programs can also purge configuration files when removing a package. Package management also handle the kind of automatic update functionality you mention. But this is for *nix only...

Any installation method that is deployed, in my mind, must 'respect' the package management of the base operating system. I get rather annoyed with multiple types of update/install mechanisms (setup.py for certain python based apps for example) that seem to circumvent OS package management programs. But there is no 'one size fits all' solution. There are numerous install frameworks (e.g. NSIS - NullSoft Install Script[Win only], or IzPack[Java - used by scala]). Again, they seem to circumvent package management on *nix machines while catering to Windows based installs.

Problem is that Windows doesn't have a package management system. There is no one simple way to install, update or uninstall. Yes, there is msiexec, but that just provides a means to an end and doesn't handle update mechanisms nor framework/standardize installs. As for update mechanisms, we're left with 3rd party programs.

Other than making sure that LibO cleans up after itself, how much effort do we want to put into installers?

Regards,
Scott Furry
