Hi,


On my system, the following is true, which is scary.

root at dancer64:/proc/1# ls root/home/dancer/Mail/inbox -d
root/home/dancer/Mail/inbox
root at dancer64:/proc/1# ls /home/dancer/Mail/inbox -d
ls: /home/dancer/Mail/inbox: No such file or directory


I am doubting the following is the correct way to figure out whether
it's a chrooted environment. Root user seems to be able to access
/proc/1/root

+chrooted() {
+  if [ -r /proc/1/root ]; then
+    return 1
+  fi
+  return 0
+}

My kernel may be a bit different since I live off git tree, so that
might depend on the kernel.
