| 19:12 | <mcgwrath> Does LTSP tie into Ubuntu's livepatch system, or since a chrootless image is created from root, one would have to recreate the image when the system is patched?
| |
| 19:36 | <alkisg> mcgwrath: livepatch is for live kernel patching; you don't reboot your clients?!
| |
| 19:36 | mcgwrath: a good policy is to run `apt full-upgrade; ltsp image /` periodically on the server, AND reboot the server and the clients
| |
| 19:37 | People that boast "567 days uptime!" should be ashamed of it, not proud :D
| |
| 19:38 | <mcgwrath> Normally the clients are always on, until I get notified that there's an update. Then I do the updates, run ltsp initrd, if needed reboot clients and then the server.
| |
| 19:39 | lol, no 500 day + uptime. ;)
| |
| 19:39 | The system is seasonal, and I have the server with me now as the site is shutdown for the winter.
| |
| 19:43 | It looks like there was an image made in April 2023 and another at the beginning of October 2023. So no, no years of uptime. :P
| |
| 19:44 | But if I do livepatch, and create an image of / every few months, that's okay?
| |
| 19:46 | <alkisg> When you get important updates on the server, run ltsp image /, and then the clients will get the updates when they're rebooted
| |
| 19:46 | <mcgwrath> I get that the clients won't have the latest and greatest *immediately*, but at least the main server will, and images (created with chrootless) will be built upon that. That's not a problem?
| |
| 19:47 | <alkisg> Livepatch is not related to security issues. It's just for the kernel; you don't want to have all the rest of the system unprotected
| |
| 19:47 | Livepatch along with selected service restarting may make sense for hypervisors on the cloud
| |
| 19:47 | It doesn't make any sense for desktop installations
| |
| 19:48 | You may even apply the updates on the server, and run ltsp image /, and the clients will get all of them on their next reboot, even if the server itself hasn't rebooted and hasn't applied the updates to itself
| |
| 19:49 | <mcgwrath> "Live-patch" - pardon, specifically an Ubuntu Pro subscription.
| |
| 19:49 | <alkisg> Don't bother with it. You care about security updates, not about livepatch
| |
| 19:50 | <mcgwrath> Right, I used the wrong term at the beginning of the chat.
| |
| 19:50 | It's security updates and patches that I'm looking for on the server, and then rolling that into the client image..
| |
| 19:51 | <alkisg> Right, do what I wrote above
| |
| 19:51 | <mcgwrath> Or am I going about this all wrong? :P
| |
| 19:51 | <alkisg> 09:46:44 PM - alkisg: When you get important updates on the server, run ltsp image /, and then the clients will get the updates when they're rebooted
| |
| 19:51 | <mcgwrath> yeah, full-upgrade and reimage /
| |
| 19:51 | Yes.
| |
| 19:51 | :)
| |
| 19:51 | <alkisg> Yes. While ltsp initrd doesn't help there, you need ltsp image
| |
| 19:52 | <mcgwrath> Nono- sometimes there's new users, client stations that are assigned a user based on the MAC address... yadda
| |
| 19:52 | (hence why sometimes initrd gets called.)
| |
| 19:52 | But yes, overall, very cool system! Much thanks. :)
| |
| 19:53 | <alkisg> ltsp initrd is needed when you update ltsp.conf, add new users or get a newer ltsp version
| |
| 19:53 | <mcgwrath> (y)

| 20:04 | <mcgwrath> Cools, I was reading your ubuntu wiki page alkisg, that's quite the list of degrees! Next on the list is server-failover. 8)
| |
| 20:09 | <alkisg> mcgwrath: yeah unfortunately I have more than 25 years of studies; I hope I won't need anything else in the future :D
| |
| 20:09 | <mcgwrath> X) :')
| |
| 20:10 | Yeah, my partner earned a PhD in forensic psych, she always jokes that she was in school for her first 3.5 decades.
