https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D194105 --- Comment #5 from Bryan Drewery <bdrewery@FreeBSD.org> --- Yup this is still relevant. A simple workaround for *startup* is to use exec.created. exec.poststart is too late if you want rc scripts depending on the zfs dataset. exec.start before /etc/rc might work but I didn't try. To be clear the "zfs jail" needs to occur between jail(2) and jexec "sh /etc/rc". --- /tmp/jail 2022-06-07 21:56:17.886298000 -0700 +++ /etc/rc.d/jail 2022-06-07 21:56:19.863706000 -0700 @@ -213,6 +213,7 @@ parse_options() echo " exec.system_user =3D \"root\";" echo " exec.jail_user =3D \"root\";" extract_var $_jv exec_prestart exec.prestart 0 "" + extract_var $_jv exec_created exec.created - "" extract_var $_jv exec_poststart exec.poststart 0 "" extract_var $_jv exec_prestop exec.prestop 0 "" extract_var $_jv exec_poststop exec.poststop 0 "" Then in the ezjail/jail.conf file something like this: # Must not set zfs_datasets or /usr/local/etc/rc.d/ezjail does the "zfs jai= l" too late (which is ignored but causes a warning) export jail_backups_exec_created=3D"zfs jail \$name backup" There is no corresponding place in the jail stop to do "zfs unjail".

In practice the "zfs unjail" piece does not seem impor= tant but I could be wrong. iocage avoids all of this by not using /etc/rc.d/jail like ezjail does. It = uses jail(8) and controls the ordering properly. --=20 You are receiving this mail because: You are the assignee for the bug.=
