Support for 10.6.8 Imaging

Please, don't remove support for installing Snow Leopard Images.

We don't care if a newer OS is required for the DS Server. But, we would really, really, like to see continued support for 10.6.8 Snow Leopard images.

Re: Support for 10.6.8 Imaging

One of the issues we have in our company is that we install OSes from 10.6.8 to 10.11.2 - the newer machines can't boot anything older than 10.11 and the older machines will not boot 10.11 (I think the maximum for that type is 10.7.5) so we have DS set to boot into a 10.11.1 image and we deploy 10.6.8 via an external HDD. Sucks but as far as I know, it is the only way round the problem...

Re: Support for 10.6.8 Imaging

I have not checked but in older days I found that 'unsupported' versions deployed fine, as long as you stay away from complex workflow steps.

Test all workflow steps in DS1.7.x, they may work fine with the unsupported 10.6.8.
All the 'admin' does is stop testing on 10.6.x, and will not put specific 10.6 steps in each script.
If they fail to work:

an other approach is to stay at the 10.6.x version.
As long as you do not miss any option offered by newer versions, you don't have to upgrade DS!

Option 2 keep your existing 10.6.8/ds 1.6.18 nbi folder, and connect to a 1.7.x DS server (repository). Ignore the version mismatch, and keep you workflow files (in the repository) untouched by the 1.7.x DSadmin.

Testing is key in all cases!

Re: Support for 10.6.8 Imaging

We don't need full support. For example, it is OK if the server requires something newer. We are even OK, if the server requires El Capitan.

But since some of the machines won't boot on anything newer than 10.6.8, it would be nice if we could make NetBoot Sets for Snow Leopard.

Our experience with the images, is that once made, DS can pretty much restore anything Mac. So, we aren't expecting that is a request that requires any effort. And if necessary, we'd be quite willing to make the images with an old version of DS, or some other method.

Re: Support for 10.6.8 Imaging

I agree with ComputerConnection and Fiavvek. We too would like to see support for 10.6.8 continue on a bit longer. In fact, it is probably our number one feature request.

Re: Support for 10.6.8 Imaging

Well, I didn't quite put it that way (or maybe I did not make myself clear enough). The issue we have is not one that I believe the developers of DS can fix. This is AFAIK only an issue that Apple can (and probably don't care about i.e. will not) fix. We have several MacBook4,1 - these will not boot anything above 10.7.5 according to Mactracker - I know for a fact that they will not boot 10.10. Now, we also supply iMac16,1 - these will not boot anything lower than 10.11! (according to Mactracker again). Even if they were to boot with 10.10, the overlap is not sufficient for us to have one subnet and be able to boot all of our Macs under the same DS server. We don't really want to put several subnets in place with two servers capable of running DS even though we can technically run that. At the moment, we just use CarbonCopyCloner to reimage the few 10.6.8 machines off an external HDD - all the others are capable of using the 10.11 NetBoot image.

Re: Support for 10.6.8 Imaging

10.6.8 was one of the best older releases, I still run it on a few things here myself

Re: Support for 10.6.8 Imaging

It is the NetBoot set that determines which Machines can be booted from it. DS Netboot sets, like normal Apple NetInstall, NetBoot and NetRestore images do NOT have to be hosted on a server of the same version. The System Image Utility should be of the same version when creating them. But they can be hosted nearly any NetBoot/NetInstall server. We have hosted images for 10.4.x through 10.11.x on the same 10.6.8 Server.

The problem is that DS seems to be dropping the ability to create the special DS Netbook sets for the older OSes. If we could create them, there is no reason to expect that we would have any problem hosting them, as we don't with the other images.

So, we don't need DS to enable older machines to boot from new OSes, nice as that might be. What we need DS to do, is to allow us to continue to create NetBoot Sets based on older OSes. That is something that they very clearly can do. And is is something that they did do for 10.6.8 up until very recently.

Re: Support for 10.6.8 Imaging

Fair enough, each company will work in its own way. You clearly need DS in a different way to the way we need it (and that is fine!). Pity that 10.6.8 is now unsupported but I suppose there is a limit to how far back you can support software (and speaking of DS here - it would have to be able to support 10.6, 10.7, 10.8, 10.9, 10.10, 10.11 - all of that takes effort that could potentially more easily be channeled into supporting a smaller number of OSes).

Re: Support for 10.6.8 Imaging

Part of this problem is caused by Apple. Rather than polish each OS until it is reliable, Apple has chosen to come out with a new OS every, year. They said this time it was different, that instead of new features, that they were going to focus on reliability, like they did with Snow Leopard.

However, instead of continuing to improve Yosemite, and to come out with a 10.10.6, a 10.10.7, etc. with fixes, they came out with 10.11 El Capitan. Which has new features,a s well as new bugs, and isn't really the reliable OS, that was promised.

But the bigger issue, is the one that developers face. These constant changes mean lots of extra work for developers. So instead of improving their products, the developers have to invest lots of time and effort just to keep things working.

But having said the above, there  are still lots of programs, that continue to run on Snow Leopard. And we would still like to see support for creating Snow Leopard NetBoot sets, for at least a little while longer. Or, even better, make it open source, so that the community can support it, if they so choose.
