           Summary: Please inform us at install time about modification to
                    vm.mmap_min_addr
           Product: Wine
           Version: 1.1.31
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: hughperkins at gmail.com


Please inform us at install time about modification to vm.mmap_min_addr , and
give us the choice of not setting it to zero.

If I understand correctly, it is only needed for 16-bit programs?  So, maybe at
install time, either:

1. a question like:

"Do you wish to enable support for 16-bit applications?  This means we need to
modify mmap_min_addr, which is a potential security risk."

, or 

2. for example, in Ubuntu packaging, we could have an optional package, like:

sudo apt-get install wine-16bit

.... which will ask the same question as in 1, and then set mmap_min_addr

For now, I have reversed the change in /etc/sysctl.d/wine.sysctl.conf , but I
would like the change to not revert every time I install a new version of
wine...
