After a long absence during the summer and working my way through moving to Berlin, I think it's the appropriate time to write a new blog post about the changes that arrived to the distribution. I have started writing this post in August, and now it's finished! Only a few months late. Since I have been holding this post for so long, there are quite a numerous details to be discussed.
Repository meta file
You might have noticed that most packages now contain a file named
file contains a small description, license for the package, and the maintainer
information of the package. A sample meta file looks like the following:
description: Carbs Packaging Tools license: MIT maintainer: Cem Keylan <email@example.com>
Inclusion of this file makes it easier to query package information, as it is
now implemented inside the
cpt-search utility. Running
cpt-search -q puts
the utility in query mode, and makes use of the package descriptions when
searching for packages. Unlike the default operation mode, using the
makes the tool output in a pretty format, which is not meant to be parsed by
other tools. The format is similar to the output of
apt search. Below is an
example of running
cpt-search -q carbs:
baselayout@/home/cem/repos/main/core/baselayout 3-1 Carbs Linux base directories / scripts / configuration carbs-docs@/home/cem/repos/main/core/carbs-docs 20201226-1 Carbs Linux documentation carbs-init@/home/cem/repos/main/core/carbs-init 1.2.2-3 Carbs Linux init scripts cl-utils@/home/cem/repos/main/core/cl-utils 1.0.1-1 Carbs Linux repository utilities cpt@/home/cem/repos/main/core/cpt 6.2.0-1 Carbs Packaging Tools
The package manager library provides the
pkg_query_meta() function to easily
meta file, which is further explained in the package manager
documentation. Also see
cpt-search(1) for more information on the flags and
The package manager now uses BLAKE3 to generate checksums, however this change
is backwards compatible, and does not break any old packages that are lying
about. If for some reason you need a package to have old SHA256 checksums, you
can generate the checksums using
cpt-checksum -s, which is what I'm using the
generate the checksums for the
cpt package itself.
Message of the Day files
With the release of the version
6.1.0 of CPT, I have added a
MOTD file for
displaying updates and important information from the repository. This file is a
simple plaintext file that should be present on the root of the repository, and
it is printed to the standard output during the
Adding the core repository to the tarball
I am thinking of adding a copy of the
core repository to the release tarballs.
By adding it, it will be a good incentive to remove the
git package from the
tarball, and let the user choose which repository backend they want to install
git/fossil/rsync) instead of enforcing
Packaging Linux Kernel headers
The kernel header files are now packaged from a separate source tarball that only contains the kernel headers so that the downloads are much smaller. For comparison, the kernel tarball is sized ~110 Megabytes, while our header tarball is 1.6 Megabytes. The sources for the headers can be found on https://fossil.carbslinux.org/linux-headers.
You can also fork the package and install LTS headers that are also provided by this repository, if they better fit your needs.
No blog post is complete without me butchering this website, trying to shove it into a different static site generation software, breaking lots of links in the process, and write it up here as if it were some sort of achievement or something. I've switched to Hugo this time, because it's obviously better(TM) than using org-publish. Well, let's see how long my position on that will last.
I have created symlinks for the time being, but you will need to update your RSS feeds for the blog and the news:
I will also no longer be serving plaintext pages, with the exception of the
installation guide. The documentation is available offline through
carbs-docs packages (in both multiple formats), and the website is clean
enough to be easily navigated through a terminal browser.
