[Rpm-maint] Single rpm that uses %post to deal with target system version differences - good idea or bad?

[Chris Markle]

Folks,

Relatively new to the rpm-building world here... From a "best
practices" or "good rpm's don't do that" point of view, what is your
counsel on having a single rpm that installs on say multiple versions
of Linux, but that uses the post-processing facility to do
version-by-version post-processing steps, specific to each different
version. I guess the point of doing this would be to have a
"universal" rpm rather than one per Linux version or versions. Is this
considered a "bad" practice to go this way? Thanks in advance for your
opinions.

Chris
