openSUSE encourages su, discourages sudo (although you can sudo all you want)

Wicked - "Managed" ifup / ifdown

Network Manager - Remembers network configurations

zypper up

Unless you "Enabled Online Repositories" during Install, you need to update to install all patches, fixes and improvements since the install ISO was built

No, really. Standard stuff you can find and read on your own

Minimal to know, makes life easier

Transactional Server

  • High Threat facing, eg Naked Webservers

  • High Availability, Minimal Downtime

Deployment Scenarios

Technical Description

  • Read-only partition or disk, LEAP only

  • Nothing can write to the mounted partition or disk

  • Updates and other changes applied only with reboot

  • With every change, a BTRFS snapshot is created, enabling simple and fast "undo"

Install

  • LEAP - Desktop Selection

  • Tumbleweed- Package Installation

Transactional Server

  • https://forums.opensuse.org/showthread.php/531246-Transaction-Server-New-TW-and-LEAP-15-server-option

  • https://kubic.opensuse.org/blog/2018-04-04-transactionalupdates/

  • https://medium.com/@lwinmaungmaung/opensuse-transactional-server-5-minute-review-9a5e85fc28b9

More Info

Do not confuse openSUSE Transactional Server with other "Transaction Servers" like Microsoft's Transaction Server which is used to manage data transactions over a network
