Red Hat's rpm contains a %attr(-,root,root) directive that overrides

generally fakeroot is not needed with rpm. Simply use %attr to set
the ownership as you require them to be set. You will still see the
builder's ownership in the .rpm file (e.g. rpm2cpio) but at
installation time the ownership will be set by rpm explicitly.
Minor point (don't let it distract from the main point of the thread),
this is incorrect. rpm alters the file data when STORING data into
the embedded .cpio, not when EXTRACTING. rpm2cpio | cpio -itv will
reveal the %attr attributes, not the on-disk attributes at build time.
Hmmm, not per-se. None of the info in cpio headers is used by rpm
(other than
the path name), so %attr() is set by rpm -Uvh when EXTRACTING.
However, I have a dim memory of generating the cpio headers from %
attr rather
than from the staged file in $RPM_BUILD_ROOT like 4-5 years ago in
order to
simplify QA to diff'in rpm -qlp against rpm2cpio ... | cpio -itv, and
so that rpm2cpio
would result in a largely (cpio has its own special pains) identical
install.
So %attr is used both STORING and EXTRACTING iirc.
And fakeroot (or any equivalent LD_PRELOAD scheme) can be used, but
is largely unnecessary.
