Ah! So we're talking about user specific data huh.
Generally speaking, users take a very dim view of an installation
modifying anything they have modified, so I think that supporting
rollback is probably not appropriate in this instance.
My next question would be this. Why is your installation modifying files
that, from what you have said so far, appear to belong to something
else? (You have said that the target text file is only used by one
component, but it seems the target file is not a part of that component
otherwise you wouldn't be appending to it). It's fair enough if the
modifications are in shared configuration files and there is no other
option, but otherwise I wouldn't consider it good behavior in an
installation. (I don't know what others around here think... hopefully
someone else may chime in soon!) At the very least, you should probably
also provide a user interface allowing them to decide if they want your
installation to make those changes.
I guess I'm still missing something here....
Regards,
Richard

It's simpler than that.
I have a few text lines I need to append into an existing text file.
This target text file will be used only by *one* component, in my own
single installation.
However, once the installation is complete, the user might add (on his
own, manually) more text lines - after the lines my installation added.
