Quoting George Kontostanos <gkontos.mail@gmail.com> (from Tue, 29 Mar 2011 17:57:49 +0300): > I thought that jails would be a good candidate for dedup. So far I am using > it without any issues in my /usr/src and /virtualBox directories. No idea about your problem, but ezjail is already doing some dedup. The basejail is the dedup-place, and the jails do a null-mount of it. Inside the jails are only some links to the basejail. So if you do not install the same programs (the same packages, so make sure there is no different compile timestamp (some programs have this) inside the newly generated binaries) or data inside the jail-specific area, you will not have a benefit from this.
