Smart PM for upgrade the full image

Smart PM for upgrade the full image

Hi All,

I have several targets deployed in multiple sites. Each target might  be
running  a different version of the product rootfs image. When I release a
new rootfs image I would like to use the smart command on each target at
the customer site to upgrade the software to the latest image. Going
through each package and install it separately is inefficient way of
handling the upgrade and I don't expect the customer to have the knowledge
for doing so.

What we really need is a smart command to compare the latest rootfs image
and install, remove or un-change packages based on what is currently
installed.

Can the smart command achieve that or do I need to write my own script?

Thanks,

Isn't this the same question you asked the other day? i.e., this is "smart 
upgrade".

Cheers,

Hi Paul,

Thank you  for your replay.
Smart upgrade only upgrades packages that is currently installed. It
doesn't install new packages nor remove unwanted packages.
Is that not true?

Thanks,
Tarek

That is true, yes. As far as I know, smart has no capabilities in this area 
beyond what is offered through conflicts - and for situations where one package 
replaces another, with any of the package management backends we support you 
should use RPROVIDES + RREPLACES + RCONFLICTS to ensure that the old name is 
redirected to the new name, new package is installed automatically, and the 
old package is removed (respectively).

If it's a straight old image -> new image upgrade, you'll probably have to 
look at other tools; package managers don't really handle this situation well 
- at least not out of the box.

Cheers,
Paul

Hi Paul,
Thanks for your reply.

As a work around I think I can dump a list of the installed packages from a
target that is running the latest SW.
$smart query --installed --hide-version > file.txt

Then on customer targets I could run the  install command:
$smart install `echo $(cat file.txt)` -y

At least this is going to update currently installed packages as well as
 install new ones.

I still need to write a script to remove unwanted ones.

Thanks,
Tarek
