Public bug reported: When compared to Ubuntu 23.10, creating intramfs files with update- initramfs takes 2 to 5 times more time on ARM devices.
IIUC, dracut-install usage was added to initramfs-tools to speed up the process. But now its way slower. Even running update-initramfs on jammy, which doesn't use dracut-install, is way faster then the time taken on Noble. first bad commit - https://github.com/dracutdevs/dracut/commit/3de4c7313260fb600507c9b87f780390b874c870 $ lsb_release -rd No LSB modules are available.
