  • Automating the Deployment of Freebsd & PC-BSD® Systems
    Automating the deployment of FreeBSD & PC-BSD® systems by Kris Moore [email protected] In PC-BSD 9.x every installation is fully-scripted, due to the the pc-sysinstall backend. This backend can also be used to quickly automate the deployment of FreeBSD servers and PC-BSD desktops using a PXE boot environment. In PC-BSD & TrueOS™ 9.1 and higher, this functionality is easy to setup and deploy using the “pc-thinclient” utility. PXE booting allows you to boot systems via the LAN interface, as opposed to using traditional media, such as DVD or USB. In order for clients to boot via PXE they will need a PXE capable network adapter. The initial PXE setup To get started, you will need to have a system with two network interfaces running PC-BSD or TrueOS 9.1 and a complete ports tree in /usr/ports. If you do not have the ports tree installed, you can download it by running the command “portsnap fetch extract update” as root. With these pieces in place, open a root prompt and run the “pc-thinclient” command. The first screen you see will look something like this: Enter “y” to continue, and the following screen will be shown: In this case you are going to be setting up a PXE installation server, so enter “i” to continue. (The “r” option can be used to make your system a X thin-client server. More information about this can be found on the wiki page at the end of the article.) After selecting your type of PXE system, the thin-client wizard will then begin to build the “net/isc-dhcp42-server” port.

I didn't found a quick fix for abs and other methods producing compilation errors with old gcc versions. Well, I am not 100% what is the correct solution here, but - we need to add to README that required gcc should be >= 5.0 (as older have problems with C++14 standard) - maybe add warning (or even error) to domake - we need to provide a way how to proceeed in that case, which is IMO: - install latest GCC from e.g. tarball, then provide a name of the compiler (like g++-6.1.0) to domake / make somehowe - install clang from distro package, as usually it is more OK with c++14 and again, change the compiler used by make - maybe install clang from tarball... Now how to provide the name of compiler I am not 100++ sure, but IMO either environment variable/commandline switch? Or maybe that warning in domake should try to pick the correct compiler and ask user? Let him choose?

The first player to remove all their checkers is the winner. Alternate turns with your opponent moving checkers toward your home in the upper right hand quadrant of the backgammon board. Move checkers by rolling the dice. The numbers on the dice refer to how many spaces you may move with one or more checkers. Highlights show you where the checkers can possibly move. If you roll doubles, you get to move each die twice, concluding in four moves for that turn. You may move your checkers onto any Point so long as it is occupied by your checkers, is empty, or has 1 opponent checker.
