Mock problem in EPEL 5?
 

Hi,

I am seeing a package build fail in EPEL 5 that builds fine in EPEL6
and Fedora. Specifically there seems to be a problem writing to /sbin
in the build root:

Installing Shorewall Version 4.4.22.3
install: cannot create regular file `/sbin/shorewall': Permission denied
ERROR: Failed to install -T -o root -g root -m 0755 shorewall /sbin/shorewall

See http://koji.fedoraproject.org/koji/getfile?taskID=3291843&name=build.log

Any ideas?

Cheers,
Jonathan

I'm surprised this builds at all in mock: it's trying to give away
ownership of the file to root, which is a privileged operation. If you
patch it not to try to do "-o root -g root" then it should work OK, and
the resulting files will be owned by root anyway.

Looking a little closer at the install script, it actually performs a
check to see if it is running as root, and if not doesn't set those
owner/group permissions - in other branches, this check works
correctly. So the question is, why does mock in EPEL 5 run as root,
but not in EPEL6 and Fedora? This seems like a bit of a security
issue!

It's not. Your spec file is missing a BuildRoot: tag, which is still
needed for EPEL-5. Without it, $RPM_BUILD_ROOT is not set and PREFIX
(which upstream has renamed to DESTDIR) is thus empty, and the check for
root never happens.

Oh yes, you're right. Thanks. Feeling dumb now.
