.gitlab/ci/build-host.sh:
Change all script-local variables to lower-case and make some of them overridable using environment variables (by
providing defaults).
Break down overly long commands by splitting them into a list of strings.
Use local variables where possible.
Change `main()` to use rsync instead of cp to copy the project to the build location more generically.
Change `main()` to use rsync instead of cp to copy the build artifacts on the VM from the project's build directory to
the output.
Remove all unnecessary `function` keywords for function declarations.
Replace the dependency on libisoburn's `xorriso` with libarchive's `bsdtar` and util-linux's `blkid` in
`prepare_boot()`.
Add `print_section_start()` and `print_section_end()` to reduce code duplication and error potential when printing lines
for gitlab's collapsible sections (https://docs.gitlab.com/ee/ci/jobs/#custom-collapsible-sections).
Document the script's behavior and expectations.
Document the understood environment variables and add links to documentation on understood units (in case of size
units).
.gitlab/ci/build-inside-vm.sh:
Expand the script to allow building based on mkarchiso's buildmodes.
Accept two parameters now: profile and buildmode.
Add gitlab collapsable sections by adding specific printfs for it to all functions.
Add extglob to be able to more specifically target files.
Change `create_checksums()` to also generate the legacy md5 and sha1 checksums.
Change `create_checksums()` and `create_zsync_delta()` to accept and process an unspecified amount of files as
parameters.
Change `create_zsync_delta()` to lower the blocksize when creating a file for the bootstrap image.
Change `create_metrics()` to create metrics depending on build mode.
Rename `create_temp_pgp_key()` to `create_ephemeral_pgp_key()`.
Add `create_ephemeral_codesigning_key()` to create a codesigning key, that is used to sign the netboot artifacts.
Change `run_mkarchiso()` to also create an ephemeral codesigning key before running mkarchiso and to run
`create_checksums()` and `create_zsync_delta()` with files depending on build mode.
.gitlab/ci/build-host.sh:
Call `build-inside-vm.sh` using the PROFILE and BUILDMODE environment variables as parameters.
.gitlab/ci/build-host.sh:
Change parameters to qemu's `-drive` option to make use of the explicit `read-only=on`, as the implicit `read-only` is
now obsolete.
.gitlab/ci/build-host.sh:
Change the readonly TMPDIR variable to a global tmpdir variable and set it in the `init()` function.
.gitlab/ci/build-inside-vm.sh:
Change assigning the readonly tmpdir variable directly to assigning it after declaring it.
Change `cleanup()` and `create_zsync_delta()` to use bash-style statements and also check whether SUDO_GID is set before
using it.
.gitlab/ci/build-host.sh:
Set shebang to /usr/bin/env bash to be more portable/flexible.
Turn all posix statements ([]) to bash style statements ([[]]), as we are using bash.
Terminate the list of parameters to rm or cp with --.
Replace the implementation of finding a local ISO to use with one that relies on a sorted list of potential images.
Use virtio-net-pci for networking with qemu.
Set the cow_spacesize to 4G for the archiso environment.
Use --needed in the call to pacman to not re-install already up-to-date targets.
Attempt a full system upgrade (but ignore the kernel).
Increase the timeout for when installing packages to the archiso environment using pacman to 120s, as a system upgrade
is being done as well.
Use systemctl poweroff -i to shut down the virtual machine as it is more future proof and robust.
.gitlab/ci/build-host.sh:
Add script to be run in a container with access to qemu.
It is a slight modification of arch-boxes' build-host.sh script to cater to the specific archiso requirements.
.gitlab/ci/build-inside-vm.sh:
Add script to be run in virtualized environment, established by build-host.sh.
This script builds the actual archiso profiles and creates checksum for the resulting image files.
