Subject: make.sh: Bind-mount /proc as a workaround for unshare
X-Git-Tag: v2.29-core189~65^2~52
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5e8730eb9aec83a76b3ae7719925ede8470069a6;p=ipfire-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.
