[09:31] <petski> Hi all, I would like to upgrade my (pxe) 14.04.5 image with a newer kernel than the default 4.4.0-31-generic. Which steps would you recommend? (Can I find the iso build script/procedure anywhere online? My current approach would be to unpack the latest udebs, and hack a new initrd.gz/vmlinuz, not sure if that would be successful)
[09:33] <petski> The official #ubuntu-iso channel is empty, so that's why I ask my question here. Please let me know if I'm in the wrong place.
[11:58] <xnox> petski, why don't you just download d-i builds for trusty, with updated kernel?
[11:59] <xnox> petski, see directories in http://archive.ubuntu.com/ubuntu/dists/trusty-updates/main/installer-amd64/current/images/
[11:59] <xnox> petski, i'd recommend xenial-netboot as it should have xenial kernel in it.
[12:00] <xnox> petski, or do you mean rebuild that, but get even newer than 4.4.0-31 kernel?
[12:00] <xnox> petski, just $ pull-lp-source debian-installer trusty
[12:00] <xnox> adjust kernel versions, and use sbuild to build that
[12:44] <petski> xnox, thanks for your reply, very helpful indeed!
