linaro-android-media-create fails when not running as root

[Guilherme Salgado]

If you run l-a-m-c without sudo, you'll get the traceback below. It happens because the unpacked userdata is not world readable, which causes the following line (from move_contents()) to return an empty list:
  files = glob.glob(os.path.join(from_, '*'))

Which in turn causes the move to fail as there are no files to move to the userdata disk.

mv: missing destination file operand after `/tmp/tmpdTw_YS/userdata-disc'
Try `mv --help' for more information.

thanks salgado!

subscribed linaro-release ...

could be release noted or we can ensure that our default instructions posted should just refer to sudo linaro-android-media-create.

[Alexander Sack (asac)]

should get fixed for 11.06 ... guess thats 0.4.9. maybe milestone there.

[Mattias Backman (mabac)]

It always works for me without sudo. Unpacking the userdata.tar.bz2 file gives all the files my user and group as owner. I wonder if that's just lucky since I perhaps happen to have the same user id as the packed data.

uid=1000(mabac) gid=1000(mabac) groups=1000(mabac)

[Guilherme Salgado (salgado)]

Indeed, looks like it will work without sudo if you run l-a-m-c with a user whose uid/gid is 1000. This is the permission of the files in the tarball:

drwxrwx--x 1000/1000 0 2011-05-26 11:42 data/
drwxrwx--x 1000/1000 0 2011-05-26 11:42 data/app/
