A problem has been reported where tar will freeze while extracting the default bundles archive to a networked Application Support folder.
From the bug report (Michael Kuron):
File servers tested: SMB on OS X 10.9.3, AFP on OS X 10.9.3, AFP on OS X 10.6.8, SMB on Windows 2008 R2.
Multiple machines tested.
Using ‘gnutar’ from MacPorts does not show the problem.
Setting ‘COPYFILE_DISABLE=1’ before running tar does not show the problem (the workaround used in this commit).
