[pkg-lxc-devel] Bug#847048: Bug#847048: lxc: centos6 fails to start after u/g to 2.0.6

[Dean Hamstead]

It might be something that lxc-start needs to check based upon some 
config parameter. I dont know if there is a way of getting info from the 
ABI or if its just a matter of checking the kernel version and/or 
/proc/cmdline.

Such a config parameter could then be placed in the centos6 template and 
others as needed. At start up, lxc-start could then fail gracefully with 
a helpful message?
