Hello, lxc containers(krb5_get_init_creds_password) will be the first mainline containers to offer functionality similar to solaris zones. They aim to go mainline completely in 2.6.29 and lot of code is already is place. See http://lxc.sourceforge.net/lxc.html. Although lot of functionality is already in the current kernel, the options are not configured. $ zgrep -i namespace /proc/config.gz CONFIG_NAMESPACES=y $ uname -a Linux presario 2.6.28-ARCH #1 SMP PREEMPT Sun Jan 25 09:43:53 UTC 2009 x86_64 AMD Athlon(tm) 64 X2 Dual-Core Processor TK-57 AuthenticAMD GNU/Linux Will it be possible to add relevant kernel options? There are userspace tools available as well, which could go in another package. Is this the right way to ask for new functionality or a new ticket is required? -- Shridhar
