Just updated to the latest kernel with no problems.
I dont want to reimage my entire usb rootfs and setup from scratch.
Is switching the repo url's to buster another safe to upgrade? Otherwise im just going to let it be.

Yes. It is safe. But I would backup this USB rootfs first before upgrade.

Here is how I usually do backup and restore:

Thanks for the assurance and I did the backup first. Everything seems to function fine.

But i took a look at some of the logs and these messages stood out. So i dont know if something from my old config files isnt compatible now. Anyone opinion are these worth bothering with?

dmesg:

edit: the PID stuff i resolved by editing each service file under /lib/systemd/system/smbd.service for example.
Just deleted the /var. Based on this bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=928864

I have no opinion regarding systemd. I consider that something everybody needs to deal with after they installed my basic rootfs and run Debian successfully (with sysvinit).

Pickle,

Yes. When this happens, set up a swap file.

checked my dmesg and so far it looks like just adding the

vm.min_free_kbytes = 65536

has resolved the issue (no kernel panics). I did not create a swap file.

Yes this is more important than swap file. Still, the swap file is very helpful during boot.

heck, it makes swap even more important. If you're going to reserve that much memory you'll end up needing to swap even sooner.

:) agreed.

For boxes such as this one or less RAM such as Dockstar with 128M, I would say keep it at:

vm.min_free_kbytes = 16384

thanks for the feedback!

so im booting off a usb and i dont really care to add the swap there.
and ive already used the full drive for my shares.
my conclusion is just add a swap file to one of my shares.

root@NSA320:/sharedfolders/share1# cd /export/share1/
root@NSA320:/export/share1# fallocate -l 2G swapfile
root@NSA320:/export/share1# chmod 600 swapfile 
root@NSA320:/export/share1# mkswap swapfile 
Setting up swapspace version 1, size = 2 GiB (2147479552 bytes)
no label, UUID=5092f9a4-060e-4bd2-8581-3e565666fe17
root@NSA320:/export/share1# swapon swapfile  
root@NSA320:/export/share1# vi /etc/fstab (i added /export/share1/swapfile swap swap defaults 0 0)
root@NSA320:/export/share1# swapon --show
NAME                    TYPE SIZE USED PRIO
/export/share1/swapfile file   2G 264K   -2

after this i could see the swap from a client so I put a . in the name and now i cant see it through nfs

root@NSA320:/export/share1# swapoff swapfile
root@NSA320:/export/share1# mv swapfile .swapfile
root@NSA320:/export/share1# vi /etc/fstab (changed the path to include the period)
root@NSA320:/export/share1# swapon .swapfile
root@NSA320:/export/share1# swapon --show
NAME                     TYPE SIZE USED PRIO
/export/share1/.swapfile file   2G   0B   -2

i also adjusted /etc/sysctl.d/99-sysctl.conf

vm.min_free_kbytes=16384
vm.swappiness=60

I still need to reboot and see that the fstab entry works as expected, but I cant yet until a operation finishes on the server

That's the ideal parameters for small NAS such as this one. I run all my 128MB plugs with this setup.
