When I attempt to remove package with pysetup remove 'package-name' on Fedora 17 - it fails with:
'my-package' cannot be removed
Error: [Errno 18] Invalid cross-device link
strace'ing showed that there was an attempt to call rename from package dir into /tmp which is tmpfs.
Proposed fix is trivial - use shutil.move instead of barebone os.rename.

How did you install my-package?

pysetup install.
strace of removal looks like this:
stat("/home/nekto0n/workspace/pillar/penv/lib/python2.7/site-packages/ygroup/__init__.py", {st_mode=S_IFREG|0664, st_size=0, ...}) = 0
rename("/home/nekto0n/workspace/pillar/penv/lib/python2.7/site-packages/ygroup/__init__.py", "/tmp/ygroup-client-uninstalljkoIAl/__init__.py") = -1 EXDEV (Invalid cross-device link)

OK. Can you paste the full traceback for the error?

Sorry, no traceback by default, had to augment with "raise" :) Now output looks like this:

Thanks! As your message shows the problem is in the install module, I propose to close this bug as a duplicate of Alexis’ bug about improving d2.install. The new FileMover class should use shutil.move, and we’ll make sure to test install+remove as you did to see if the bug is gone.

glad to help
