Relevant code in Makefile.pre.in is this line within the "bininstall" target: (cd $(DESTDIR)$(BINDIR); $(LN) python$(VERSION)$(EXE) $(PYTHON)) This translates to this in the build log (see e.g. http://koji.fedoraproject.org/koji/getfile?taskID=1930186&name=build.log) (cd /builddir/build/BUILDROOT/python-2.6.4-6.fc13.x86_64/usr/bin; ln python2.6 python) and for python3 (e.g. http://koji.fedoraproject.org/koji/getfile?taskID=1930070&name=build.log): (cd /builddir/build/BUILDROOT/python3-3.1.1-17.fc13.x86_64/usr/bin; ln python3.1 python3) It's a hardlink, not a copy. In the following, note how both /usr/bin/python and /usr/bin/python2.6 are names for Inode 93896: [david@brick ~]$ stat /usr/bin/python File: `/usr/bin/python' Size: 5916 Blocks: 16 IO Block: 4096 regular file Device: fd01h/64769d Inode: 93896 Links: 2 Access: (0755/-rwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2010-02-11 07:58:36.147851467 -0500 Modify: 2010-01-25 13:24:26.000000000 -0500 Change: 2010-01-26 03:37:39.571857466 -0500 [david@brick ~]$ stat /usr/bin/python2.6 File: `/usr/bin/python2.6' Size: 5916 Blocks: 16 IO Block: 4096 regular file Device: fd01h/64769d Inode: 93896 Links: 2 Access: (0755/-rwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2010-02-11 07:58:36.147851467 -0500 Modify: 2010-01-25 13:24:26.000000000 -0500 Change: 2010-01-26 03:37:39.571857466 -0500 ...and from rpm -qlv python: -rwxr-xr-x 2 root root 3564 Jan 25 13:24 /usr/bin/python lrwxrwxrwx 1 root root 6 Jan 25 13:24 /usr/bin/python2 -> python -rwxr-xr-x 2 root root 3564 Jan 25 13:24 /usr/bin/python2.6 ...note the "2" in the link count column, whereas /usr/bin/python2 is a symlink to the first of the two names.

It looks like I was in error when I wrote the material referring to this bug that's now in the preamble of https://fedoraproject.org/wiki/Packaging:Python, and that they will require a slight rewording. Sorry about this.

Updated by removing the pull box noting this bug and changing the paragraph about system runtimes to this: One of these python runtimes is the "system runtime" which is what we run when invoking <code>/usr/bin/python</code>. On Fedora 13 this is <code>/usr/bin/python-2.6</code> (In reply to comment #4) > Updated by removing the pull box noting this bug and changing the paragraph > about system runtimes to this: > > One of these python runtimes is the "system runtime" which is what we run when > invoking <code>/usr/bin/python</code>.

Description of problem: Both python2 contains a ${_bindir}/python file which is a copy of its python interpreter (/usr/bin/python2.6). Instead, it should be a symlink.
