1               Mono(tm) Binary Kernel Support for Linux
2               -----------------------------------------
3
4To configure Linux to automatically execute Mono-based .NET binaries
5(in the form of .exe files) without the need to use the mono CLR
6wrapper, you can use the BINFMT_MISC kernel support.
7
8This will allow you to execute Mono-based .NET binaries just like any
9other program after you have done the following:
10
111) 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
252) 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
333) 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
37if [ ! -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
46fi
47
48# Register support for .NET CLR binaries
49if [ -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
54else
55        echo "No binfmt_misc support"
56        exit 1
57fi
58
594) 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.
