BTW, this command disables the exec-shield functionality for all the processes
running on the system, which may be a bit unwise...
There is a command called setarch, which allows to disable exec-shield on a
per-proces basis. Simply call "setarch i586 wine <arguments>" and it will start
wine with exec-shield disabled, while other processes will still be protected
by it.
I'm not using Redhat/Fedora, but I patched my kernel with exec-shield to improve
system security; I'm running wine from a simple wrapper called swine :-)) (for
"setarch wine") and I have no problem with it...
WIth regards, Pavel Troller
