FreeBSD and Docker

[opendaddy at hushmail.com]

Hello everyone!

Thanks a lot for your input.

Any chance I could use something like overlayfs / zfs like the author claims?

Do sign up and give your feedback. There used to be a FreeBSD thread @ meta.discourse.org but it just got deleted.

Many thanks!

O.D.
