Hi,
could somebody add a mention of adding INSTALL="install -p" to argument
of 'make install' as a fix of preserving the time stamp during install
to the packaging guidelines?

This really should be in the spec file templates as well, since it's
such a common packaging bug (and shouldn't break anything either).
Well, you are a new-comer to packaging, aren't you?
Otherwise you'd likely know that "install -p" is highly controversal,
because it doesn't guarantee consistency of timestamps and is mostly
"eye-candy".
I consider myself an old stager, nevertheless I hear this for the first
time. Can you please tell me where this was discussed in the past? I
couldn't find anything on fedora-devel or fedora-packaging.
Ohh, it has been discussed numerous times, so many times I don't have
any particular reference to one of these.
The points behind these discussions are:
* People believe in "timestamps" matter for rpm.
rpm doesn't and must not care about timestamps, otherwise share files
between packages doesn't work.
All "install -p" does in such situations is using different timestamps
than when not using "install -p"
- Many packages don't use "INSTALL" (automake generated Makefiles do)
- Using INSTALL="install -p" basically is eye-candy, assuring timestamps
on "non-generated installed files" match with those inside of the
sources. On generated files (generated scripts, headers, compiled
binaries/libraries ...) it doesn't have any impact.
All "install -p" does in such situations is using different timestamps
than when not using "install -p"
- Many packages don't use "INSTALL" (automake generated Makefiles do),
some use "INSTALL" in a completely different meaning.
I think you tend to describe your POV as the only valid one - even on
controversial topics.
Well, I don't do so. I am saying "INSTALL=install -p" is stylishness and
functionally mostly meaningless.
