[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 5/7] osstest: introduce a FreeBSD build script
In order to generate the FreeBSD installer image and the install
media.
The install sets are the vanilla ones generated by the 'ftp' release
target. The installer image is handcrafted based on the filesystem
created by the 'bootonly' target, which is then populated with the ssh
host keys, and setup in order to use the serial console. The other
difference from upstream FreeBSD installer images is that the one
built by osstest uses a ramdisk instead of relying on the installer
media to be somehow attached, either on a CD or USB drive. This is
required in order to boot the image from pxelinux (where no CD or USB
is actually attached to the host, and everything is fetched from
tftp).
Due to the nature of the FreeBSD build, the outputs are different from
what osstest expects from a buildjob, more specifically
path_freebsddist points to a folder that contains the several outputs
form this buildjob.

Changes since v1:
- Remove the ts-build-check FreeBSD hack.
- Use pkg-static instead of pkg.
- Introduce buildcmd_stamped_logged_root and target_cmd_build_root.
- Use target_cmd_build_root and buildcmd_stamped_logged_root in the
ts-freebsd-build script.
- Fix the script snippets to use <<END.<<'END' in order to avoid
escaping the shell variables.
- Set path_freebsddist runvar to point to the folder where the build
files are stashed.
- Add a comment at the top of the file describing what runvars are
consumed/produced by the build script.
