Installation Guide/Configure Ramdisk
From ParabolaWiki
Generate initial RAM-disk
- If you need special boot features, such as for disk encryption, configure /etc/mkinitcpio.conf accordingly (see mkinitcpio). In any case, re-generate the initial RAM-disk with:
# mkinitcpio -p KERNEL
... where: KERNEL is the one that you chose in the "Install a kernel" step (eg: linux-libre, linux-libre-lts). If you have installed multiple kernels, run the same command again for each kernel.
