I really don't understand the method here.
Can you reproduce any issue ? or do you have received informal
informations that the posttrans script wasn't working for a reason ?
Because for now It's working fine with me all the time, so there is
probably an unknown corner case here.
Reproduce, no, but I've had a couple of occasions where I was not able to
get to graphical boot. I just read about the need to run depmod on a Fedora
thread. I didn't think about that so I manually erased the RPMs and let
akmod rebuild them which fixed the problem.
yes , after install kmod you should load the kmods modules , it may work
without it , because X load it but we should ensure modprobe nvidia.ko (not
depmod .. )
The documentation has always said that you need to reboot once the
driver is installed/updated (and immediately after).
1/ Because that's easier than to restart any process that have the
wrong (mesa) libGL.
2/ Because nvidia driver use some kind of contiguous memory that might
not be available after the boot.
3/ Because it relies on certains kernel boot options that was set by
the package, so you need to reboot anyway.
for example VirtualBox instructions:
dnf install VirtualBox kernel-devel-$(uname -r) akmod-VirtualBox
akmods
systemctl restart systemd-modules-load.service
It could be possible to use a
trigger on systemd-modules-load.service
after kmod-foo will install.
At least it would be a generic way to solve the problem when a given
kmod drops a /usr/lib/modules-load.d file
This should be handled by kmodtool at least. But I would prefer that a
reboot is documented (the less is done on user's back, the better).
