But these are not the only ways that dot net abuses the installer. All of the
patches bundled with SP1 are of exactly the same structure - i.e. a transform
T1toU1 (and special transform #T1toU1), and a cab file PCW_CAB_NetFX.cab . The
worst part is that some (read: NetFX_CA.msp) patches have a completely empty
cab file yet add a media entry nonetheless. So our media source handling gets
botched since we don't expect conflicting stream filenames, or media entries
with no files. All of the patches have overlapping file sequence numbers as
well, so we need to do offset these numbers. (And as I found out, you also need
to offset sequence numbers from files that have their sequence number changed
by a patch).

These patches fix all these problems and let the installer install all of the
files. However afterwards the installer still crashes, but it seems like for a
different reason.

Could an MSI guru look at this and say whether the direction of the patches at
least right? I recognize that "msi: offset file/patch sequences and media
diskids to prevent conflicts when applying a patch" is a mess and should
probably be moved out of action.c
