add support for the kernel names we have to make changes to both lp:maas and lp:maas-images(used to generate the images and kernels at <a href="http://images.maas.io">images.maas.io</a>). The changes to lp:maas I can do and test with unit tests but I need the actual packages to make the changes to lp:maas-images. The sooner the packages are available the sooner we can do real world testing and get the streams up.<br><br></div><div>Q: MAAS currently has the ability for an administrator to set a minimum kernel version allowed to be used with a machine. If a user selects an older release an hwe kernel will be automatically selected to meet the minimum kernel version set by the administrator. Users are preventing from deploying with an older kernel than what the administrator has set. I'm wondering how this restriction should work with low latency kernels. Currently I'm leaning towards forcing the user to stick with the kernel flavor(generic or low latency) the administrator set as the minimum hwe kernel. I was wondering if you or anyone else on the kernel team had any preference?<br><br></div><div>Thanks,<br><br></div><div>Lee<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Aug 9, 2016 at 12:44 PM, Leann Ogasawara <span dir="ltr"><<a href="mailto:leann.ogasawara@canonical.com" target="_blank">leann.ogasawara@canonical.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote">On Fri, Aug 5, 2016 at 12:22 PM, Leann Ogasawara <span dir="ltr"><<a href="mailto:leann.ogasawara@canonical.com" target="_blank">leann.ogasawara@canonical.com</a><wbr>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div><div>On Fri, Jul 29, 2016 at 1:09 PM, Tim Gardner <span dir="ltr"><<a href="mailto:tim.gardner@canonical.com" target="_blank">tim.gardner@canonical.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div><div>On 07/29/2016 10:37 AM, Andy Whitcroft wrote:<br>
