Handling *.rpm packages

[jbj]

I'd like to see the update-engine handle RPM packages.

If that functionality is of interest, then please poke an RFE to
<rpm-...@rpm5.org>
and I'll be happy to assist with the effort.

Actually, that should work today. When Update Engine detects a new version of your product (which is installed via rpm), it will download the new software on a disk image, mount the disk image, and run the .engine_install script at the root of that dmg. That .engine_install script could then use "rpm" to install the new software. 

Is that what you were asking for?

Not quite, but perhaps enuf.

Let me ask the question a different way:

    What are the formats (like *.dmg) that update-engine can handle?

Apologies for not (yet) studying update-engine code & doco ...

Update Engine currently requires downloads ("Codebase" in the server
plist) to be dmgs. But this is just a way to package up things,
similar to tar, zip, etc. We like dmgs because they contain
filesystems and can be mounted read-only after we verify the integrity
of the dmg.

Of course, there's no technical limitation preventing support for zip
files or even rpms, if there was such a need.

HTH,

So dmg only atm. Perhaps a FUSE mounted rpm package would be best.
