Here's the wrapper script I used for that
$ cat $HOME/usr/bin/git-spam
#!/bin/sh
dohelp() {
echo "syntax: $0 TO-ADDR REV-LIST"
}
if [ -z "$2" ]; then
dohelp;
exit 1
fi
TO=$1
REV=$2
shift

git send-email --compose --to "$TO" --smtp-server=smtp.corp.redhat.com --no-chain-reply-to $REV "$@"
Assuming you do your work on a branch, then you can just run
git-spam libvir-list@xxxxxxxxxx master..
If you were doing your work on master directly, then you'd
have to use
git-spam libvir-list@xxxxxxxxxx origin/master..
Or explicitly specify the starting commit hash.

Looks good.
I wonder if we should also have an explicit 'unconfined' string to
simplify life for people who want to run the container entirely
unconfined ? eg avoid them needing the verbose
-s static,label=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

You'll need to re-add the code to detect selinux in configure, since we
had got rid of that previously. eg create m4/virt-selinux.m4 containing
AC_DEFUN([LIBVIRT_SANDBOX_SELINUX], [
fail=0
old_LIBS=$LIBS
old_CFLAGS=$CFLAGS
AC_CHECK_HEADER([selinux/selinux.h],[],[fail=1])
AC_CHECK_LIB([selinux], [fgetfilecon],[],[fail=1])
LIBS=$old_LIBS
CFLAGS=$old_CFLAGS
test $fail = 1 &&
AC_MSG_ERROR([You must install the libselinux development package in order to compile libvirt-sandbox])
])
And then add
LIBVIRT_SANDBOX_SELINUX
to configure.ac, and update libvirt-sandbox/Makefile.am to include
SELINUX_CFLAGS and SELINUX_LIBS.
And make libvirt-sandbox.spec.in have a BuildRequires: libselinux-devel

Can you add line wrap at appropriate places

This SEE ALSO section should have some line wraps add too
