Subject: [PATCH lxc] Revert "initutils: use vfork() in lxc_container_init()"
This reverts commit d65e5e492f740bbb50e3005f97420c3ddae3d595.
With vfork the child process modifies the parent's memory,
so the calls to `signal`, `fprintf` and regular `exit` may
be dangerous and might cause conflicting states in the
parent.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Wolfgang Bumiller <w.bumiller@proxmox.com>

Subject: [PATCH lxc] use 2 sysfs instances for sys:mixed
In order to facilitate this, the default mount list's
'destination' may now be NULL to mean that the source should
be unmounted instead.
Here's what we need to do:
1) Ensure the first sysfs mount point is writable.
2) Mount a read-only sysfs on /sys
3) Bind devices/virtual/net *writably* into /sys
We use /proc/sys as a staging directory for the first sysfs
mount in read-write mode, then mount /sys r/o. Afterwards we
bind the r/w devices/virtual/net and unmount the staging
/proc/sys mount point.
The staging directory would not be required with the new
mount API, but this way we can support the old API and keep
the general workflow in the `default_mounts`.
Once we drop support for the old mount API, the
default_mounts table could just get a subdirectory field to
mount subdirectories directly.
