I would like to do this on Tuesday, 18 January. Switching this to be the default installer would happen a few weeks after that, pending discussion on release formats with the release engineering team. This should provide a sufficient testing period before 9.0 and allow a maximal number of bugs to be discovered and solved before the release is shipped.

> The primary goal of BSDInstall is to provide an easily extensible installer without the limitations of sysinstall, in order to allow more modern installations of FreeBSD. This means that it should have additional features to support modern setups, but simultaneously frees us to remove complicating features of sysinstall like making sure everything fits in floppy disk-sized chunks.

> BSDInstall is a set of tools that are called in sequence by a master script. These tools are, for example, the partition editor, the thing that fetches the distributions from the network, the thing that untars them, etc. Since these are just called in sequence from a shell script, a scripted installation can easily replace them with other things, (e.g. hard-coded gpart commands), leave steps out, add new ones, or interleave additional system modifications.

> This provides functionality most similar to the existing sysinstall 'Express' track. It installs working, bootable systems you can ssh into immediately after reboot on i386, amd64, sparc64, powerpc, and powerpc64. There is untested support for pc98. The final architecture on which we use sysinstall, ia64, is currently unsupported, because I don't know how to set up booting on those systems -- patches to solve this are very much welcome.
> There are still some missing features that I would like to see in the release, but these do not significantly impact the functionality of the installer. Some will be addressed before merging to HEAD, in particular the lack of a man page for bsdinstall. Others, like configuration of wireless networking and ZFS installation, can happen between merge and release. The test ISOs are also lacking a ports tree at the moment, which is a statement about the slow upload speed of my DSL line and not about the final layout of releases.

Technical discussion (bug reports, for instance) should be directed to the freebsd-sysinstall list only. Most other discussion belongs on -sysinstall and -current.

I dont follow the freebsd-sysinstall and freebsd-arc list so sorry if
this has already been discussed. From what I have seen pc-sysinstall
already does all these things, and can install freebsd. Therefore why
are we reinventing the wheel?

I don't mean this as any disrespect to the work you have done.
