Only the fetch downloading the content is different. Many jails are established by linking directories between the jail and host to save disk space. Learning FreeBSD jails with manuals, handbook, and source code repository Elvin Aslanov · Jul 9 FreeBSD Jail Management FreeBSD jails is a containerization (lightweight virtualization) technology Build and install a kernel including VIMAGE, epair and briged interfaces Configure the kernel: (/usr/src/sys/i386/conf/JAILKERNEL) include GENERIC cpu I686_CPU ident JAILKERNEL # Virtual networking for jail options VIMAGE device epair device if_bridge # The nullFS to mount local directory I have heard about jails many times since my early days of FreeBSD life but it was only the last year I began to use it in production. This article is a sort of personal notebook where I summarize what I learned about jails. It would be frequently updated as I learn more. Assumptions The host is running FreeBSD 11.2/amd64 on ZFS. Each jail has a separate root dataset under /vm on the host. From outside the jail, the program jexec may run a program from inside the jail: % jexec myjail program Archiving a jail % ezjail-admin stop myjail % ezjail-admin archive myjail % ls /usr/jails/ezjail-archives/ See also.
