Howdy,

I was playing around with LXC containers this past weekend, and
noticed a couple of issues with the lxc-fedora script:

#1: Line 96 should be ${ROOTFS}/etc/sysconfig/network instead of
${ROOTFS}/sysconfig/network

#2 Line 249 contains a reference to $PKG, which isn't used in the
program. I adjusted the variable to point to the correct package, and
use this in the calls to yumdownloader:

    PKG="${DISTRO}-release.noarch.rpm"
                   .....
    yumdownloader --destdir="${CACHE}/partial" "${PKG}"

#3 The $CACHE/partial path is escaped unnecessarily:

   RPM="rpm --root \"${CACHE}/partial\""

#4 The program assumes yumdownloader will work, which isn't always the
case. I added an if statement to check the return code:


   echo "Downloading distribution release file ${PKG}"
   yumdownloader --destdir="${CACHE}/partial" "${PKG}"
   RESULT=$?

   if [ "${RESULT}" != "0" ]; then
       echo "Enable to download the distribution release file"
       exit 1
   fi

#5 The package name passed to yumdownloader is incorrect:

   yumdownloader --destdir="${CACHE}/partial" "${DISTRO}-release.noarch.rpm"

   On Fedora 10 and 11, this evaluates to:

   fedora-release.noarch.rpm

   When we need it to evaluate to:

   fedora-{RELEASE_VER}.release.noarch

   This is fixed in the PKG variable listed above.

A patch that addresses these issues is attached.

Thanks,
- Ryan

The current code implies we have to define a utsname in order
to unshare it. This problematic in case of system container because
we want them to set their hostname. As the utsname namespace is
a COW, we can safely unshare it in all the cases.

Stupid me, we don't want to add a dependency to an external

Just let lxc to define a .pc file, so the upper layer will

The checkpoint / restart code is too experimental regarding
the current implementation in the kernel.
As there are several implementation and we don't know which
one will be merged upstream, I remove the code and add a few
parameters to checkpoint.

The checkpoint/restart function will be plugins in order to choose
the CR solutions. This approach will allow to switch from one
implementation to another without breaking anything.
