I have this link to a French Blog : http://blog.etoilebsd.net/post/Emprisonner_une_debian_dans_un_FreeBSD This describe how to "jail" a Linux Debian in FreeBSD. I hope this will help you. I haven't used it. Thanks to its author : Baptiste Daroussin. I translated it in English : <<<<<<<<< # mkdir /home/jails/debian # mkdir /home/jails/debian/dev # mkdir /home/jails/debian/proc # mkdir /home/jails/debian/sys # kldload linux # kldload linprocfs # kldload linsysfs # kldload lindev # mount -t devfs none /home/jails/debian/dev # mount -t linprocfs none /home/jails/debian/proc # mount -t linsysfs none /home/jails/debian/sys We are using /home/jails/debian for the root of the Linux Debian. We will load all the necessary devices (nota : lindev appeared in Freebsd 9-CURRENT and has MFCed in 8-STABLE, it is not obligatory). We could do the install with debootstrap, but I prefered to use an openvz template : # fetch http://download.openvz.org/template/precreated/debian-5.0-x86.tar.gz And I unpack it in my jail : # tar xvfp debian-5.0-x86.tar.gz -C debian --exclude dev* --exclude proc* --exclude sys* To correctly start my jail, at least 1 service must be started in the jail (I failed to build a persistent linux jail only). By default the startup script of jails try to launch /etc/rc that we will create and launch /etc/rc.shutdown to stop it. # echo "/etc/init.d/cron start" > /home/jails/debian/etc/rc # chmod 755 /home/jails/debian/etc/rc # echo "/etc/init.d/cron stop" > /home/jails/debian/etc/rc.shutdown # chmod 755 /home/jails/debian/etc/rc.shutdown In /etc/rc.conf we configure the startup of the jail : jail_debian_rootdir=/home/jails/debian jail_debian_hostname="debian" jail_debian_ip="192.168.1.3" jail_debian_interface="nfe0" jail_debian_devfs_enable="YES" jail_debian_devfs_ruleset="devfsrules_jail" jail_debian_flags="-n debian" We start the jail : # /etc/rc.d/jail start debian And voilà : #jls JID IP Address Hostname Path 15 192.168.1.3 debian /home/jails/debian #jexec debian uname -a Linux debian 2.6.16 FreeBSD 8.0-STABLE #3: Sun Jan 10 20:39:38 CET 2010 i686 GNU/Linux #jexec debian cat /etc/debian_version 5.0.4 Here a beautiful Debian Linux jailed in FreeBSD But be careful, not everything works perfectly : sysklogd don't run cause to /dev access. But 99% is functional. --- En date de : Ven 28.5.10, Yuri <yuri@rawbw.com> a écrit : > De: Yuri <yuri@rawbw.com> > Objet: Possible to run Linux distro in a jail? > À: "freebsd-questions" <freebsd-questions@FreeBSD.ORG> > Date: Vendredi 28 mai 2010, 20h16 > When I googled "linux in a jail" I > got some references but no particular howto. > Since currently VirtualBox is broken (hangs OS after a > while), is it really possible to install Linux into a jail > as a virtual machine? > > Yuri > _______________________________________________ > freebsd-questions@freebsd.org > mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >help
