Quoting Jose Amengual <jose.amengual@gmail.com> (from Thu, 16 Oct 2008 =20 08:43:15 -0300): > Hi Guys. > > The other day I install a server with jails with FreeBSD 7 32 bit in =20 > a 64 bit capable processor. > > After I install I start wondering some things that I point out here : > > Any benefit to install 64 bit vs 32 bit with the purpose of use jails ? It depends. If you want to use more than 4G: yes. > Can I install a 32 bit FreeBSD and create 64 bit jails ? ( using =20 > ezjail or downloading the full 64 bit source to create the jail ). No. > Can I install 32 bit FreeBSD and then made a make world and change =20 > it to 64 bit ? ( is recommended ?) IIRC this depends upon your FreeBSD version. I think in CURRENT =20 there's code which supports that now. No guarantees. > Can I install a FreeBSD 64 bit and create 32 bit jails ? Sort of. You can install a 32bit world into the jail and make sure =20 32bit support is activated in the kernel. The 32bit programs will then =20 run just fine in the jail (but 64bit ones should run fine too). It's =20 the same way as you can run linux programs in a jail.
