Issues with unshare call

[gboddin]

Here is how I can now reproduce (I still have to learn CARE ;)) :

This is also happening when you try to proot -0 cdebootstrap-static (without the qemu layer)

P: Validating sysvinit
qemu: Unsupported syscall: 337
E: Failed to unshare: Function not implemented

git clone https://github.com/gboddin/debprootstrap.git -b 0.3.1 debprootstrap
cd debprootstrap
wget http://static.proot.me/proot-x86_64&&chmod +x ./proot-x86_64
mkdir ubuntu-armhf.bundle
curl -sS https://cloud-images.ubuntu.com/daily/server/trusty/current/trusty-server-cloudimg-armhf-root.tar.gz|tar -xzC ubuntu-armhf.bundle
./proot-x86_64 -S ubuntu-armhf.bundle -w /root -q qemu-arm "apt-get install binutils-multiarch" 
./proot-x86_64 -v 3 -S ubuntu-armhf.bundle -b .:/debprootstrap  -w /root -q "qemu-arm -strace" "apt-get update && apt-get install binutils-multiarch && /debprootstrap/debprootstrap armhf wheezy" 1> debprootstrap-armhf.log 2> strace-armhf.log

The 2 log files are there if needed :

• http://debproot.siwhine.net/debprootstrap/debprootstrap-armhf.log
• http://debproot.siwhine.net/debprootstrap/strace-armhf.log
