[PATCH v6 0/2] rbind mounts for /dev and /sys

[Cedric Hombourger <Cedric_Hombourger@mentor.com>]

Some of the packages I have been rebuilding within Isar require /sys mounted.
For instance, golang-google-grpc runs some package tests after it builds itself
and reads properties from /sys/class/dmi.

The initial version of this patch series only added a mount of /sys. Henning
then suggested that we follow Gentoo's guidelines for chroots. As such, this
patch series is now mounting /dev and /sys as rbind mounts but leaves /proc
as a regular procfs mount (like Gentoo does).

ChangeLog:

v6: remove unnecessary mkdir for /sys
v5: cover letter added as suggested by Jan (private e-mail)
v4: limit rbind mounts to /dev and /sys, leave /proc as a regular mount
v3: rbind mounts for /dev, /proc and /sys, add explicit umount calls
v2: create /sys directory
v1: initial submission, simply mount /sys

Cedric Hombourger (2):
  buildchroot+bootstrap: rbind mount for /dev
  buildchroot: add sysfs mount since expected by some packages
