Subject: make.sh: Bind-mount /proc as a workaround for unshare
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1c1838509c0180c331cd267a8e728497939f60ee;p=people%2Fms%2Fipfire-2.x.git

make.sh: Bind-mount /proc as a workaround for unshare

unshare seems to want to change the mount propagation for /proc
before it has been mounted. In order to workaround that problem,
we bind-mount /proc to itself before.
