What do you want in a package manager?

[Nancy Yuen]

I'm looking into package management for BMCs in our fleet.  I'm wondering
who else is interested in this, does it make sense for OpenBMC.  What kind
of features are important?  What kind of package format (rpm, deb,
something else)?

We have a distributed system dictating versions of software (BIOS, OS,
userspace packages, other firmware) which should be on a particular machine
(based a machine's characteristics like type, owner, etc). So our use case
has the BMC take a list of packages to be installed, natively installing
the packages on the BMC. Packages must be signed and verified
during installation.  There is also the concept of deviation checking.  If
the files for a package or some parts of the file system deviates from
what's expected, it triggers some kind of repair flow.
