You might take a look at my alternate patch in the patches list.  It 
doesn't rely on that sort of thing -- it relies instead on well-known 
environment variables: $SYSTEMROOT and $WINDIR.  It still has some 
OS-specific knowledge in it, in that it knows that only NT-derived OSes 
define SYSTEMROOT and uses WINDIR as a fallback for 9x systems.  I don't 
know which approach is superior.

I'm not a fan of the "if X, scream and die" bit in this original script 
or the one you've proposed.  Postinstall scripts shouldn't fail.  I 
think they should give best effort, and if they can't do what you want, 
they should simply quietly skip that bit.  Besides, this patch may be 
put into some other postinstall script, and you don't want to avoid 
doing the other tasks in that script just because the /etc/hosts part 
can't find the Windows system directory.
