Would someone know what the unit is supposed to be for the
IFPkgFlagInstalledSize?
It's one of the undocumented flags you can find in some Info.plist
and for which the unit seems to come from another galaxy.
For instance, in the Safari 1.2 package, the archive weights 21.3 (or
21.8) MB uncompressed.
In the Info.plist, IFPkgFlagInstalledSize is stating: 30718.
So we're not dealing with bytes, or KiloBytes.
In iTunes 4.something package, we have an archive of 26.1 (or 26.5)
MB uncompressed and IFPkgFlagInstalledSize is stating: 27846.
In this case, this could be some kind of KiloBytes but not the
official one.
It is indeed KiloBytes with each file rounded up to a 4k boundary,
since this is a "better" estimate of the actual space it will take on
disk. Of course the block size of your filesystem may not be 4k.
Any package with LOTS of files can have huge differences in sizes.

Any idea?
