Hi All,
A new version of the liblxc has been released, lxc-0.6.0.
This version provides a new set of features:
* take into account the devpts new instance
* we can log to the container with the tty, lxc-console
* we can use a directory or a block device as a rootfs
* lxc-debian script build a lenny debian
* various fix and improvement
One important information:
==========================
*** lxc will no longer need a patched kernel, all the kernel features
are available in the 2.6.29 kernel ***
Thanks for the contributions and the feedbacks.
Below a detailed log of the modifications:

system type.

* scripts/lxc-debian.in: Remove some pointless debian services
From: Daniel Lezcano <[email protected]>
Remove some debian services because they don't have sense in a
container, like the hw clock or the unmount of the file systems.

* src/lxc/lxc_conf.c: build a set of flags for the different
enabled subsystems From: Daniel Lezcano <[email protected]>
When we want to check if a subsystem is enabled, we look at the
presence of a file/directory in the configuration tree files.
That works until we chroot into the rootfs. Some subsystem should
be preferably setup after the chrootfs, making the code simpler
and easier to read. So before setup the different subsystem, I
build a flags set and reuse it later to check if the subsystem is
enabled or not.

* scripts/lxc-debian.in: handle interruption/failure of lxc-debian
more gracefully
From: Matt Helsley <[email protected]>
If lxc-debian fails or is interrupted during debootstrap then the
next invocation of lxc-debian breaks because it only checks for
the existence of the directory. This forces the user to remove
the cache by hand to retry the create step.
Let's allow the user to re-run lxc-debian to resume/retry. Store
the cache in a partial-$ARCH directory until debootstrap
succeeds. Then move the valid cache to its final destination.

* configure.in, src/lxc/start.c: Add signalfd function definition
From: Dietmar Maurer <[email protected]>
The signalfd function prototype and the signalfd header file is
not defined in the debian Lenny. We want to use this debian
version with a newer kernel.
This patch gives the signalfd function prototype, because the
function is available in the glibc-2.7 which is the version
coming with debian Lenny.

* scripts/lxc-debian.in: Complete use of autoconf prefix in
lxc-debian
From: Matt Helsley <[email protected]>
The lxc-debian script does not consistently address the lxc lock
as @LOCALSTATEDIR@/lock/subsys/lxc. Make consistent use of the
autotools substitution to completely enable configure --prefixes.
I also added a comment explaining why some of the paths didn't
need autoconf substitutions for anyone who wants to understand
the script. Also, to separate it from the container contents
proper, I moved the CACHE variable initialization above the
container-internal path variables.

From: Daniel Lezcano <[email protected]>
Fixed the type of the opt variable. On the powerpc architecture,
that leads to an infinite loop in the getopt inspection because
getopt returns 255 instead of -1 as expected. The opt variable
should be an int and not a char.

Rights are not yet supported - anyone can use the tty of any
container. Resizing of the tty is not supported - and probably
won't be.
