(I'm interested in plain Requires, not Requires(post) etc.)
Requires and Requires(post) are equal in ordering except for
loop-breaking purposes. When no loops are present, both guarantee the
files are there. When dependency loops are involved rpm makes an
educated guess to cut it but obviously there can be no absolute guarantee.
I dispute the “obviously” part, with regard to unpacked files. :)
But as I understand it, RPM does not distinguish between unpacking and
configuring as a far as dependencies are concerned. This means that
when it comes to %post scriptlets, dependencies are far stronger than
with Debian's dpkg, and the cycle-breaking mechanisms are required more
often.
Correct, rpm does not distinguish between unpacked and configured. It
doesn't make much difference since it does not support delayed script
execution.
