Subject: [PATCH] 99-kdump.conf: Omit hwdb dracut module
|
|
|
|
The hwdb (udev hardware database) file `/etc/udev/hwdb.bin` is currently
|
|
included in the initramfs, taking up approximately 13MB of space. This is
|
|
a significant size for kdump initramfs, which may lead more OOM issues.
|
|
|
|
Certain advanced device initializations that rely on hwdb (e.g., custom
|
|
keyboard mappings, specific touchpad configurations) may not work in the
|
|
kdump environment.
|
|
|
|
However, kdump do not require hwdb in the most cases, as critical devices
|
|
like storage, network, and basic input devices are typically handled by
|
|
standard udev rules and kernel drivers.
|
|
|
|
This change prioritizes reducing initramfs size over retaining hardware
|
|
database functionality, as the latter is rarely critical in the kdump
|
|
environment.
|
