Package: lxc Version: 0.6.5-1 Severity: minor Hello,
this is a list of pitfalls and observations when I started using lxc:
* The manpage for lxc-create refers to templates as "lxc-debian,
lxc-busybox". The actual usage is without the lxc- prefix e.g.
"-t busybox". Please clarify in the manpage.
* A container created using "-t busybox" will fail to start if the
busybox package is installed instead of busybox-static. I'd suggest
to check whether the busybox binary is actually the statically
linked one, and check for presence before that:
$rootfs/dev/shm"
+ [ -x /bin/busybox ] || return 1
+ ldd /bin/busybox | grep -q 'not a dynamic executable' || return 1
mkdir -p $tree || return 1
* The lxc-debian script is not in the search path and thus not usable
as in "lxc-create -t debian". Unless you have good reason for that
this should be changed.
* lxc-debian again: In the "remove pointless services in a container"
list, module-init-tools is surely another init script that does not
make sense in a container.
* The documentation uses the IPv4 address/network 1.2.3.5/24 as
example. That is a public IP and actually routed. To avoid harm,
please change to addresses reserved for documentation, e.g.
192.0.2.0/24 (RFC 5737).
On a side node, lxc support is broken from 2.6.32.3 up to and
including 2.6.32.9. If you learn about error messages like in
# lxc-start -n busybox /bin/busybox ash
+ lxc-start: failed to clone(0x6c020000): No space left on device
+ lxc-start: No space left on device - failed to fork into a new namespace
This is fixed in upstream commit
933b0618d8b2a59c7a0742e43836544e02f1e9bd and hopefully in 2.6.32.10,
too.
