Comment:
I've made no changes to this patch. Michael has refused to give it a
positive review, since he claims (in the review above and in person) that
the flags file is deleted and rewritten whenever the install moves.
However, he's wrong. I just read the code and there is exactly *one*
place that the flags file is written:
{{{
16 # Write the flags file if it isn't there.
17 if not os.path.exists(flags_file):
18 write_flags_file()
}}}
Since flags_file is never deleted, and is only written when the flags_file
doesn't exist, it can't be deleted or overwritten when the install moves.
So I don't see what the problem is.
