Viraniac (viraniac) wrote : performance regression in dracut-install

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.
