This is the tree for petalinux.

https://github.com/Xilinx/linux-xlnx/tree/xlnx_3.8

I am looking for sysvinit package,which contains things like init ,halt etc. When this source code is compiled we get corresponding binaries in /sbin/. I found after compiling binary files like init.sysvinit,halt.sysvinit etc.

I can download the source code separately from here But the same package must be there in petlainux source also. How do I search these source code in petalinux tree above?

  • Can't say for sure but I think based on a quick check that petalinux perhaps uses busybox in place of sysvinit. Note that most normal linux distributions, other than debian, don't use sysvinit anymore (but they don't use busybox either). – goldilocks Apr 9 '14 at 11:04
  • Is Busybox an alternate to Sysvinit? And yes I have seen an option for busybox in the Configuration GUI of petalinux – gpuguy Apr 9 '14 at 11:28
  • Yes (it's more than just that though). Sysvinit is a specific implementation of the init daemon fundamental to all *nix style systems; busybox can serve a similar purpose. Init is the first process started by the kernel during boot. – goldilocks Apr 9 '14 at 12:33

You linked to a Linux kernel source tree. You won't find sysvinit there (nor any other program) because this is only the kernel, not a complete Linux distribution.

This Xilinx repository collection doesn't include sysvinit or any other init that I can find. The wiki mentions using BusyBox for userland tools, and says to download the upstream sources. BusyBox includes an init program.
