[PATCH][Documentation]Add BINFMT_MISC support for Mono .NET-basedbinaries
From: Felipe Alfaro Solana
Date: Mon Mar 29 2004 - 03:05:18 EST
Just as there is documentation for BINFMT_MISC and Java bytecodes
support, I thought it could be interesting to add documentation on how
to add BINFMT_MISC support for directly running .NET ".exe" binaries
using the Mono CLR.
Attached is patch against 2.6.5-rc2-bk3 but should apply against
Please, consider it for inclusion. Thanks!

+ Mono(tm) Binary Kernel Support for Linux
+To configure Linux to automatically execute Mono-based .NET binaries
+(in the form of .exe files) without the need to use the mono CLR
+wrapper, you can use the BINFMT_MISC kernel support.
+This will allow you to execute Mono-based .NET binaries just like any
+other program after you have done the following:
+1) You MUST FIRST install the Mono CLR support, either by downloading
+ a binary package, a source tarball or by installing from CVS. Binary
+ packages for several distributions can be found at:
+ Instructions for compiling Mono can be found at:
+ Once the Mono CLR support has been installed, just check that
+ /usr/bin/mono (which could be located elsewhere, for example
+ /usr/local/bin/mono) is working.
+2) You have to compile BINFMT_MISC either as a module or into
+ the kernel (CONFIG_BINFMT_MISC) and set it up properly.
+ If you choose to compile it as a module, you will have
+ to insert it manually with modprobe/insmod, as kmod
+ can not be easily supported with binfmt_misc.
+ Read the file 'binfmt_misc.txt' in this directory to know
+ more about the configuration process.
+3) Add the following enries to /etc/rc.local or similar script
+ to be run at system startup:
+# Insert BINFMT_MISC module into the kernel
+if [ ! -e /proc/sys/fs/binfmt_misc/register ]; then
+ /sbin/modprobe binfmt_misc
+ # Some distributions, like Fedora Core, perform
+ # the following command automatically when the
+ # binfmt_misc module is loaded into the kernel.
+ # Thus, it is possible that the following line
+ # is not needed at all. Look at /etc/modprobe.conf
+ # to check whether this is applicable or not.
+ mount -t binfmt_misc none /proc/sys/fs/binfmt_misc
+# Register support for .NET CLR binaries
+if [ -e /proc/sys/fs/binfmt_misc/register ]; then
+ # Replace /usr/bin/mono with the correct pathname to
+ # the Mono CLR runtime (usually /usr/local/bin/mono
+ # when compiling from sources or CVS).
+ echo ':CLR:M::MZ::/usr/bin/mono:' > /proc/sys/fs/binfmt_misc/register
+ echo "No binfmt_misc support"
+ exit 1
+4) Check that .exe binaries can be ran without the need of a
+ wrapper script, simply by launching the .exe file directly
+ from a command prompt, for example:
+ NOTE: If this fails with a permission denied error, check
+ that the .exe file has execute permissions.
