Good night,

I love using Gentoo on my workstations. The main problem I'm facing, is that it requires too many time (really too many interactive attention time, for rebuilding the kernel, etc etc...) in all the updates of the system. I have been thinking that perhaps I could in some manner build the system in some fast machine, later build the packages and fetch all that packages from all my machines. As said, I'm talking about workstations, not servers having one or two services and fewer dependencies than a desktop system with a graphical interface as KDE Plasma.

Does anyone have experience in handling in some, more easy manner or more comfortable manner the update of the laptop, home desktop pc, work desktop pc, etc...... what is your experience with Gentoo in this kind operations?

Best regards,

There are several methods to achieve this. The optimum solution requires more information. What are the different hardware configurations? Intel? Amd? mixture of both? etc.

The easiest case is if everything is very simular. In that case you can have your fastest machine build all its software and place that build in a network share. All the other computers need do is download and install it. Portage naively includes the tools to do this and the network share can be made via ntfs or samba according to taste. Of course, the fast box has to build to the least common architecture so your new computers would miss out on some of their optimizations. Some quality time reading the appropriate documentation should illuminate the exact method.

For a while I had a laptop and desktop with identical cpus and gpu (the integrated intel) and missions so the laptop never had to compile a thing. For more diverse applications the slower machines will have to build their specific programs.

Apologies if I take a while to respond. I'm currently working on the dematerialization circuit for my blue box.

Hi!

Thank you so much for your answer. I would have no problems in building a couple or three package families each one for the needed cpu (that would be done silenty by a fast machine :) ). The main thing I was trying to do was, to have the most comfortable updates (such as in any binary package distribution)... I'm pretty busy from some time ago to present, and I like Gentoo... but....

Anyway, there is a os part, with packages having don't know.. the cryptsetup or lvm binaries... the own ls.... all that can be packaged in such commented way?... even they are not pure userland packages as for instance, KDE Plasma?.

For the Kernel... even if you use, olddefconfig or similar make possibilities, how do you usually manage it?. Do you usually build with Genkernel a generic kernel and that's all?. I usually do a genkernel to invoke menuconfig in order to customize it and so... but it's a forcibly dedicated time when doing that, which is sometimes not able to be dedicated....

Thanks a lot for sharing your opinion,
Cheers!
