I'm actually considering that. I still have one or two slack boxes on
ADM A4s here. They are teaching boxes mostly.
There is in the Manjaro package for the kernel the instructions in the
shell that create the kernel. They run:
post_install () {
# updating module dependencies
echo ">>> Updating module dependencies. Please wait ..."
depmod ${KERNEL_VERSION}
echo ">>> Generating initial ramdisk, using mkinitcpio. Please wait..."
mkinitcpio -p linux${BASEVER}
and then
if [ -f /usr/sbin/update-grub ]; then
update-grub
So essentially then run a depmod on the kernel version, which is what I
was especting and seemingly missing in other documentation
adn then it makes the initramfs with a file that I'm not sure how it was
produced
man mkinitcpio
-p, --preset preset
Build initramfs image(s) according to specified preset. This may be
a file in /etc/mkinitcpio.d (without the .preset extension) or a
full, absolute path to a file. This option may be specified
multiple times to process multiple presets.
[ruben@stat13 ~]$ ls /etc/mkinitcpio.d/
linux310.preset linux314.preset linux319.preset
where these come from, I don't know. It is yet another level of uneeded
obstruction.
The whole initiation ram disk is something I'm struggling with at this
point. It has gone from a conveinence for booting to another level,
especially with systemd. I have a quote from another user that sums it
up like this:
QUOTE:
Mind you that an initramfs (or initrd) isn't really necessary under all
conditions. An initramfs /might be necessary/ if you're using a
distribution which uses systemd rather than sysvinit or a sysvinit-based
init system *and* you have /usr on an separate filesystem, or you have the
root filesystem on an LVM volume ─ in which case, you would need a
separate /boot as GRUB doesn't understand LVM. The initramfs created with
dracut will then contain the necessary tools to mount /usr and/or support
LVM.
Likewise, the kernel does not support LABELs or UUIDs, so if you want to
use those in GRUB, you'll need to create an initramfs, which has the tools
necessary to handle LABELs and UUIDs. On the other hand, if you have a
GPT partition table, then the kernel command line does support PARTUID,
i.e. the *GPT partition UUID,* which is a different thing from the
*filesystem UUID.*

Any distro should be capable of doing that :)
Maybe I should just call Patrick.
