Hi Jan Willem, it's an issue with the 'initscripts' Debian package, in /etc/init.d/mountdevsubfs.sh Hopefully it's only temporary: it also breaks UML http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=386945 The DOSEMU source code could probably work around it by mmap()ing READ|WRITE and then mprotect it with EXEC. But maybe at some future point someone will restrict mprotect() to report EPERM in such situations too for security reasons. Anyway. another way to work around it is to change $_mapping. If you set it to "mapashm" or "mapfile" then dosemu should work again.
