I would suggest checking (in CPackDeb generator code) whether if CPack
has been called in a fakerootED environment. This can be done by
checking whether if "FAKEROOTKEY" env var is defined or not.
If fakeroot is already in action then one should not call fakeroot again
(whatever the fakerootED user is).
Hmmm, unfortunately it does not work. This variable does not exist on
the fakerooted shell. I think there is no "good" way to detect that we
are in a fakerooted environment because their purpose is to mimic the
commands as if the real root user is entering them (and introspection
should not be possible by design).
I see two technical solutions:
- either using the system tar: this would not work in the case of cross
compilation (and in some circumstances only) but would work in the other
case. I believe that all the debian packaging tools are just using the
system provided tar, so this should closely mimic the debian-packaging
machinery better,
- or using a CPACK variable to avoid having fakeroot executed
I see several workarounds/hacks:
- executing with fakeroot in cpack first and in case of failure falling
back to run tar without fakeroot
- detect if the current user is root already
