For #4, you can also include pkglist inside pkglist with "INCLUDE":
[]$ cat cudafull.rhels7.ppc64le.pkglist
#INCLUDE:compute.rhels7.pkglist#
#For Cuda
kernel-devel
gcc
pciutils
dkms
cuda
[]$

Subject: [EXTERNAL] Re: [xcat-user] Stateful provisioning customization
1. Syncfiles is a default postbootscript, so its supposed to run on every
deploy. If its not running, check your postscript table to make sure its
there as a default. You can call it again if you think a package install
is overwriting one of your custom files, just add it to the node
postbootscipt line in the desired order
2. Otherpkgs works fine, the difference is it runs as a postbootscript
after the reboot, as if you were running a yum command from the OS (as
opposed to stateless which packages them up in the image)
3. For stateless there really is no "image" as fas as I know, all
customizations are handled with OS/group/node definitions and postscripts.
I don't like to mess with the osdef too much other than the syncfiles.list
and otherpkgs stuff. Kepp in mind, you can create any script you want, for
example to install extra rpm's after the main os deploys but before the
reboot (like say mellanox drivers, that may require a reboot)
4. I don't think so, but again if you need other packages just create a
script with a yum command and attach it to the group/node def
postbootscript or posctript line (making sure your order is what you want).
Thanks,

Hello,
I'm doing an stateful install right now, and I have some questions to
those who use the stateful method. Since I'm already used to
stateless provisioning I'm trying to adapt it's concepts to stateful.
So here we go:
1. Can I use syncfiles to issue "updatenode all -F" when needed?
The ideia is to have a custom file with the synclist and run a
command similar to: chdef -t osimage -o
ol8.4.0-x86_64-install-compute
synclists="/install/custom/install/compute.synclist"
2. Otherpkgs works in stateful profile?
Can I add otherpkgdir and otherpkglist to -install images? It will
install the packages during the provision phase? There's any use case
for it?
3. Where should I do the customization inside the image?
On stateless I just chroot after "genimage", do whatever I need to
do, change confs, enable/disable service, etc, and them "packimage".
How can I achieve something similar with stateful nodes?
4. Can I have multiple pkglist and otherpkglist files?
The ideia here is to keep the default ones from xCAT untouched and
just add additional ones separated by commas in osimage definition.
Thanks all.
PS: I did some reading before, but I was only able to find precise
information, I've only found for hierarchical clusters and specific
cases like CUDA, and finally I'm not sure which is "The Right Way
(tm)" to achieve the functionality mentioned.
