Hi all, FYI we landed this patch  to
avoid nested freezer cgroup support check for old kernel versions. Please
reply to this thread if you had concerns about this update.

This does not seem to me as a disruptive change, so I'm +1.

No, we need to support CentOS7 which uses 3.10 (some variant)

User namespaces require >= 3.12 (November 2013). Can we make that the minimum?

Update the *Minimum Linux Kernel version* supported on Mesos

[Andrei Budnik]

Hi All,

We would like to update minimum supported Linux kernel from 2.6.23 to
2.6.28.
Linux kernel supports cgroups v1 starting from 2.6.24, but `freezer` cgroup
functionality was merged into 2.6.28, which supports nested containers.

If anyone uses older Linux kernel version, please let me know!

Best,
Andrei
