Description Paul Eggleton 2013-12-10 12:35:57 UTC 
If you set PACKAGE_CLASSES = "package_ipk package_tar" then you'll get a number of errors during a build:

ERROR: Creation of tar /media/large/tmp/deploy/tar/libc6-dbg-2.18-r0.tar.gz failed.
ERROR: Creation of tar /media/large/tmp/deploy/tar/eglibc-pic-2.18-r0.tar.gz failed.
ERROR: Creation of tar /media/large/tmp/deploy/tar/libx11-dbg-1.6.2-r0.tar.gz failed.
ERROR: Creation of tar /media/large/tmp/deploy/tar/libx11-staticdev-1.6.2-r0.tar.gz failed.
...

If you look at the log you can see what is happening:

tar: .: file changed as we read it

I think this is probably related to do_package_write_ipk and do_package_write_tar running concurrently, and temporary files being written to and then removed from PKGDESTWORK by the former during its operation. Assuming that's the case, we just need to ignore those files as we have for the other package backends.
