In jails, I'd like a local ZFS /, a read-only nullfs-mounted /usr, and a local /usr/local. (I'd also have read-only nullfs-mounted /bin, /lib, /libexec, but let's forget about that for now.)
This way, I can upgrade the master /usr once, in one place, and have all jails inherit it. And my dear jail inmates can install anything in /usr/local (such as their favourite packages/ports). I.e., things should look like this: /myjail/ zfs /myjail/usr nullfs ro /myjail/usr/local zfs There is no problem to make this happen by issuing a handful of commands manually after boot, but I cannot seem to get it to work automatically, with existing boot mechanism. The problem is that the mount of /usr will be attempted before ZFS has mounted /myjail, the jail's root. ZFS maintains its own mount table. It is possible to disable the automated mounting in ZFS by specifying the pseudo mountpoint "legacy", and then--according to the FreeBSD manual--mount it with mount(8). Unfortunately, FreeBSD's mount seems unable to perform mounts of ZFS volumes. How can I achieve the result I want after a reboot? (The reply "use ezjail!" is not the right one. :-) It does not do what I want to do. I dislike its symlink forest, and that it creates just one ZFS filesystem for the entire jail.) -- Torbjörn _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
