If you are using mint, delete the preference that stops snap from installing (as it is required for lxc)

Debian at this time does not have lxd so you'll need to use snap:

How Do You Apply Changes You've Made?
You can make all kinds of changes to the switch, but remember they are not actually active until you run the "commit" command. This means adding or deleting config options will not have any effect until you run "commit".
Under configure mode:
It really seems limited in that it can mainly give you the things you would see on the physical unit such as load etc..

If you get kernel panic errors in VBOX usually disabling Nested Paging will fix the issue (thanks to Mark).

In most of the Cisco router IOS I find the ports like ge0/0 ge0/1 and ge0/2 or whatever your ports are down. They will not even give you a link light. So one of the first tasks should be getting the port you are working with up.
In my case the first goal is often connectivity with the LAN and WAN.
LAN = your local area network (eg. in the office/home )
WAN= your ISP/public internet (eg. fiber/cable/dsl/ethernet).........

systemd is like the service manager for your Centos and other modern Linux distributions (including Debian/Mint/Ubuntu) allows you to enable services, stop them, restart them, check their status and even reboot your system.
The key commands or arguments you will use with systemctl are the following:

Essentially a program I was running for mining did not terminate properly with Ctrl+C it is listed as defunct and cannot be killed, kernel is tainted and normal tricks to disable the port are impossible the dev and sys entries for the device cannot be browsed or interacted with in any form without a lockup of the request. The only solution is to reboot due to the kernel taint as far as I can find so far.

I bricked one of my cards by following a guide from UNRAID.
Step #1 from them wipes out the BIOS, but guess what? The step where you restore the BIOS should have been done first, which is sas2flash but no version supports or is able to find my Perc 6/i. So now I'm a bit stuck.
I tried using megarec but it's funny that it can wipe the BIOS but can't forcefully reload it:

Sometimes I work with embedded systems/custom kernels without any of the fancy init scripts and other common Linux basics that most would expect.

I tried the "Central Backup" option and it does not warn that your server gets shutdown instantly in order to do the backup!
Further, there is no way to pause or cancel the backup. Thankfully this is a test/small disk usage VPS but what if someone was running something production with a large filesize?
Ihaven't used QuickBackup but hope that isn't the same thing.

Different distributions such as Debian and Centos behave differently when trying to shutdown your system.
shutdown -H now on Debian does not do what you'd expect. The system won't power down, it will halt and do everything but power down.
shutdown -PH now will do the job though (actually power the system off). This is important to test especially if you are not near the system. If you just use -P it forcefully shuts off which is not........
