Partitioning in the installer
by Demi Marie Obenour 01 Nov '25

01 Nov '25

I'm working on updates and am very close to getting something that at least runs. However, the installer doesn't support more than three partitions, so I have to create the others manually. Where would the best place to address this be? I'm not sure if this needs a patch to the installer's C source code, or if I should fix it in a script somewhere. -- Sincerely, Demi Marie Obenour (she/her/hers)

[PATCH 0/3] Switch from mdevd to systemd-udevd in root filesystem
by Demi Marie Obenour 01 Nov '25

01 Nov '25

systemd-udevd provides support for significantly more hardware than mdevd does. Therefore, switch to it. The last patch intentionally uses some packages built with glibc to avoid having to build the world from source. The use of glibc isn't essential and is just because not using the binary cache to build is very, very slow.

Best practices for submitting tree-wide changes
by Demi Marie Obenour 01 Nov '25

01 Nov '25

In some cases, the same change should be made to many parts of the codebase. This includes things like adding set -o pipefail to shell scripts or moving command substitutions to their own commands. Should one send a single patch that makes all the changes, or should one send a bunch of tiny patches? Preferably, the answer should be added to the documentation so people don't need to ask again :) -- Sincerely, Demi Marie Obenour (she/her/hers)
