citadel-tool now installed with a hardlink for each binary tool and
dispatches on the exe path to the tool implementation. This makes
the build faster, uses less disk space, and makes it easier to
create new small tools.
Now if a variable is not set in a realm config file (or the file does
not exist), the 'global' config file will also be searched in the
parent directory (ie: /storage/realms/config). If the variable is
still not found, the value from the default instance is returned.
Main change in building images is that an empty 4096 byte block is
prepended to raw image before compression so that upon decompression
the header can be written without having to shuffle around decompressed
image.
This makes it possible to calculate sha256sum in place on an image file
which has both a header and an appended dm-verity tree. Before this
required a message process of extracting the body into a temporary file.
--just-choose will print information about which partition would be
chosen to install a rootfs image.
--skip-sha will avoid checking the sha256 sum of the image file. This
is mainly meant for use by the installer since the sum has already
been confirmed
Option takes a string argument which identifies the channel which should
be expected when mounting images. The channel name can optionally be
followed by a colon and a hex encoded public key for the channel.
The initial hashtree is generated during the yocto build, so we
want to use veritysetup from the path (to use cryptsetup-native)
rather than try to find veritysetup on the build host.
