1                Mono(tm) Binary Kernel Support for Linux 
2                ----------------------------------------- 
3  
4 To configure Linux to automatically execute Mono-based .NET binaries 
5 (in the form of .exe files) without the need to use the mono CLR 
6 wrapper, you can use the BINFMT_MISC kernel support. 
7  
8 This will allow you to execute Mono-based .NET binaries just like any 
9 other program after you have done the following: 
10  
11 1) You MUST FIRST install the Mono CLR support, either by downloading 
12    a binary package, a source tarball or by installing from CVS. Binary 
13    packages for several distributions can be found at: 
14  
15 	http://go-mono.com/download.html 
16  
17    Instructions for compiling Mono can be found at: 
18  
19 	http://www.go-mono.com/compiling.html 
20  
21    Once the Mono CLR support has been installed, just check that 
22    /usr/bin/mono (which could be located elsewhere, for example 
23    /usr/local/bin/mono) is working. 
24  
25 2) You have to compile BINFMT_MISC either as a module or into 
26    the kernel (CONFIG_BINFMT_MISC) and set it up properly. 
27    If you choose to compile it as a module, you will have 
28    to insert it manually with modprobe/insmod, as kmod 
29    cannot be easily supported with binfmt_misc.  
30    Read the file 'binfmt_misc.txt' in this directory to know 
31    more about the configuration process. 
32  
33 3) Add the following entries to /etc/rc.local or similar script 
34    to be run at system startup: 
35  
36 # Insert BINFMT_MISC module into the kernel 
37 if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then 
38         /sbin/modprobe binfmt_misc 
39 	# Some distributions, like Fedora Core, perform 
40 	# the following command automatically when the 
41 	# binfmt_misc module is loaded into the kernel. 
42 	# Thus, it is possible that the following line 
43 	# is not needed at all. Look at /etc/modprobe.conf 
44 	# to check whether this is applicable or not. 
45         mount -t binfmt_misc none /proc/sys/fs/binfmt_misc 
46 fi 
47  
48 # Register support for .NET CLR binaries 
49 if [ -e /proc/sys/fs/binfmt_misc/register ]; then 
50 	# Replace /usr/bin/mono with the correct pathname to 
51 	# the Mono CLR runtime (usually /usr/local/bin/mono 
52 	# when compiling from sources or CVS). 
53         echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register 
54 else 
55         echo "No binfmt_misc support" 
56         exit 1 
57 fi 
58  
59 4) Check that .exe binaries can be ran without the need of a 
60    wrapper script, simply by launching the .exe file directly 
61    from a command prompt, for example: 
62  
63 	/usr/bin/xsd.exe 
64  
65    NOTE: If this fails with a permission denied error, check 
66          that the .exe file has execute permissions.
