I see, but the coLinux driver might not start at all.  That and this is 
not sysv, it's windows, keyboard and mouse drivers are known to not load 
when expected, why expect anything else to function on time?

This is frailly standard, it's an array of ansi strings.  
http://www.java2s.com/Code/C/Data-Type/Arraysofstrings.htm

As you are correct StrCpy will likely not work with an C Data-Type like 
a string, let alone an array of C strings.  NSIS is a higher level 
language, so this atom would need to be mapped to a higher level 
construct.  As this whole structure is, with '\0' being replaced with 
';' I'd just assumed this case too was handled...  Perhaps by another 
interpreter, like VB...

Sorry for the NSIS specific question!!!
