For the record, I can confidently predict that the intended reference was Change Control Request, an essential element of a controlled environment with complex local configurations and/or locally developed software. In any well run shop of that kind, any code/configuration push to production must first be tested in development and sometimes staging environments, and only then pushed to production. The steps to be taken get designed as scripted actions (the deployment procedure) along with equally scripted steps to reverse the changes (the backout procedure), described on a standard format and circulated to peers for review as a document called a Change Control Request. When the CCR has gotten appropriate signoffs (other people being sometimes needed for that, too), then a rollout time gets scheduled and an Ops staffer assigned to do it. Both the deployment procedure and the backout procedure would include test steps required to verify or disconfirm successful completion. The Ops person carries out the CCR steps including if necessary the backout procedure, only halting when the production environment tests as stable. I worked for many years at a reasonably large firm that ran many Web sites, and no changes to production of any kind were permitted without CCR tracking. As the OP mentioned, running things via CCRs does not _necessarily_ imply use of change control software (Puppet, Chef, cfengine, Ansible, etc.), though it would be perverse IMO not to use it in any significant deployment. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
Re: [DNG] ifstat.eth0 on Boot
How new is the laptop? What is the model of network card? Without knowing anything about your hardware or configuration I would first check no other device like wireless is trying to connect. If it's not and the router/dhcp is definitely not doing something stupid: Then probably you should check your bios for helpful settings, and then try installing firmware in /lib/firmware for your device, like linux-firmware-free or linux-firmware-nonfree from the repo. Or use a backported kernel.

Not necessarily. Some distros are better for easy customizing than others, but in the end you can always run your own package repos (which, in fact, I'm doing regularily). OTOH, the question often is, whether customizing is really worth the effort for a particular use case. > I get that maintenance is an issue, but only > because software growth has become disproportionate. if there wasn't so > mush software < software to manage it all and there would be even less software, just > look at the number of different software build systems there are. Correct, much of today's software as grown insanely huge and complex. Browsers (and GUI stuff in general) are probably the best example of ugly bloat code and bad engineering (beginning w/ lack of modularity). IMHO, we should work closer w/ upstreams and other distros to improve the packages step by step. Sometime this also requires some radical steps. > Do one thing! do it well! Correct. But look at the commercial projects Mozilla: they're trying to roll their operating system, completely ignoring basic concepts like modularity and package management, and are pretty learning resistant. At some point you'll have to decide whether it's worth to invest any resources at all or just drop the whole code completely. > I have already hit issues in Devuan that have been inherited from > Debian.

At that point we could go that route consequently and introduce a strict separation between an init-OS and an main-OS, maybe even move to some container environment.

Aeons ago, I've been maintainer of an LFS derivative (l4g) - that was a really good learning experience, but I wouldn't use it for production. For some use cases, I'd rather think of building customized images via PTXDist, maybe run them in chroots or containers. > Has anyone here have actual practical experience of using LFS to build > anything moderate (or larger).

[DNG] Fw: Request for comments - training room
- Forwarded Message - From: Tim Wallace To: Steve Litt Sent: Tuesday, December 4, 2018, 7:13:06 PM ESTSubject: Re: [DNG] Request for comments - training room This thread reminds me of the reason I haven't been able to switch from Debian to Devuan on my server: LTSP support. LTSP is a great way to run an X server on an older machine, with all the authentication handled by the server. Haven't seen anyone mention it, perhaps because although it's in the repository, it doesn't work. The build_client script fails, using the generic system option. LTSP shouldn't be that hard to get working in Devuan, since it's worked for years with many various systems, pre systemd. Thinking of filing a bug, but thought I'd mention this here. I got my dad's machine and my laptop on Devuan, but stymied by LTSP on the server... --Tim On Tuesday, December 4, 2018, 2:06:17 PM EST, Steve Litt wrote: On Mon, 3 Dec 2018 13:42:36 + Rowland Penny wrote: > On Mon, 3 Dec 2018 13:22:40 + > g4sra wrote: > > > > Interestingly little mention of workstation BOOTP, NFS Root, Cloning > > On Boot.

I think what Roland was getting at here is the number of users and how they are dealt with makes a huge difference. At one extreme, you have 28 seats, each one of them has a user such as "user1", and you can simply use /etc/passwd & /etc/shadow to manage that single user one each seat. You could probably build one software image and simply image all 28 machines with that one image. At the other extreme, every person has their own login and can use any seat at any time (and there are hundreds or even thousands of them) so that progress/results can be logged for each person. In this case, you will really need a centralised user management such as Roland described using Samba & AD. You could still image each machine from one common image - but you'll need to do some post-imaging setup to give each machine a unique set of identifiers etc for the AD to work properly. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

This one is where the users don't have their own login - they all use just the same login, so can sit down at any machine and use the single login that's configured on the machine, and there's no need for any user management on each machine other than setting up the one user login. That might be appropriate if the training system handles user management etc. Otherwise, I agree with you. If you could set up such a scenario, then yes, your way could be used, but there was a mention of a server. If you have a server, you usually get files saved and read, so how do you differentiate between user 'fred' from computer18 and 'fred' from computer23 ?
