Ok, I did some checks and will add some patches for discussion.

[[[
fix incorrect definition of "failonerror" in <sysinfo> docu.
]]]
sysinfo-task-docu-error.patch


sysinfo-replace-propname.patch:
this is a first implementation to replace "sys.env.ProgramFiles(x86)" 
with "sys.env.ProgramFiles_x86_"
There is still the docu change missing. But I will provide this when we 
are going this way.

Result:
--- snip ---
   [sysinfo] sys.env.ProgramFiles = C:\Programme
   [sysinfo] sys.env.ProgramFiles_x86_ = C:\Programme
--- snap ---


[[[
sort sysinfo properties when using verbose="true"
]]]
sysinfo-verbose-sorted.patch:

This patch will output properties on sorted order in verbose. I found 
that I need to search more than I like to find my replaced property 
without this sorting

So far Dominik
