Need to do some catch up on “Transactional Server” from Open Suse
Posted by jpluimers on 2021/05/28
Transactional Server to me smiles like Microsoft data warehouse era, so seeing it in an OpenSuSE Tumbleweed install made me wonder: huh, DBMS?
So I likely need some catch up to do do on this:
Apparently “Transactional Server” is an installation type similar to “Server”, which can upgrade without touching a running system.
So how can the system then run with the updates applied?
The answer seems to be “reboot”.
This is contrary to a lot of update changes in the past (that seems to be towards “update the running system, even allow for live kernel patching” with optional before/after snapshots.
It immediately associates with “immutability”, and likely containers.
Hopefully I’m right, but I still have questions, like:
- why “snapper rollback” does not suffice not any more?
- how to change from “Server” to “Transactional Server” and back?
- if only
/is read-only, but others like/etc,/srv, and/varare not, how does that affect transactionality?- (you can use [WayBack] findmnt(8): find filesystem – Linux man page to list all mounted file systems)
