- When updating packages, we first create them with a temporary names
and only after all files from payload have been created this way,
the files are renamed to the final target. This means that performing
an update temporarily requires roughly twice the disk space (and inodes)
compared to the final result on per-package level. Which matters
when space is tight, such as presumably in RhBug:872314.
- Simulate what happens on upgrades by adding block and inode delta
to the equation: installing a file always consumes an inode and
the specified amount of disk space. But when replacing files,
reduce the size-delta from disk consumption *after* checking for
problems in a given DSI.
- Also fixes inode accounting which has been broken for forever (since
