Right now, rollback is mostly necessary because the package is installed
directly without checking for problems first. Checking that the packing-list
won't cause trouble means rollback won't be necessary in many cases...
considering that @exec/@unexec pairs mean rollback isn't safe in many cases,
avoiding rollback alltogether looks like a good idea...
I don't have working code yet, but my plans include trying to figure out
a somewhat larger set of packing-list features, so that exec/unexec and
install/deinstall scripts won't be needed as much, because exec/unexec
install/deinstall mean you can't answer a few useful questions by just
looking at the packing-list with an automated tool:
- what files does a package install/create/modify ?
- can you rollback from any point during the package installation ?
