commit 44cdc19b436008f03af3c1c4f5c82fa0ce8a26e6 Author: Frederick Grose <[email protected]> Date: Sat Sep 17 12:35:03 2011 -0400 Enable resize and squashing progress reporting option. Provide optional parameter to package(), _stage_final_image(), and mksquashfs() and 'show-squashing' code to mksquashfs() to permit progress reporting to the terminal. Insert the '-p' option for percentage completion reporting in the resize2fs call arguments. diff --git a/imgcreate/creator.py b/imgcreate/creator.py index deb9d95..a6a1b39 100644 --- a/imgcreate/creator.py +++ b/imgcreate/creator.py @@ -729,7 +729,7 @@ class ImageCreator(object): """ subprocess.call(["/bin/bash"], preexec_fn = self._chroot) - def package(self, destdir = "."): + def package(self, destdir = ".", ops=None): """Prepares the created image for final delivery.
