Linux grill 4.1-4.dmz.1-liquorix-686 #1 ZEN SMP PREEMPT Debian 4.1-6 (2015-08-04) i686 GNU/Linux

Behaves very well on my Stinkpad T43, less so on the Toshiba (overheating like a boss).

Yeah, liquorix also seems to behave the best on my Thinkpad x201. I wonder if that is a somewhat common relationship

Linux Bonecaster 4.4.4-pf #1 SMP PREEMPT Sat Feb 13 22:18:03 WIB 2016 x86_64 GNU/Linux

Been distro-hopping like mad this weekend (cheer Chef). Same custom kernel config for arch, debian sid, alpine, and crux at the moment.

Same setup in X (bspwm, urxvtd, compton, sxhkd, mksh as login shell, and uhhhhm ssh and gpg agent), Yes my setup isn't lightweight at all... xD same hardware, didn't turn any systemd (fuck you networkd and journald) units off, gave me :

41 MB on Crux
56 MB on debian sid with systemd
65 MB on arch ( Systemd 228 on arch needs several configs turned on like freezer-cgroup, inotify, and some debugging ones)
80 MB on alpine-linux ( intel driver on X needs fbcon, fb, and a gajillion more modules to start. So much for being advertised as 'lightweight')

Under BBQ Bork, the amount of RAM usage at start is a whooping ... 46 MB. Good enough for me.

la la la la la la..... :)

kernel-config diff (between systemd and sysv / openrc) : https://transfer.sh/qyfxH/sysd-frankie.diff

EDIT: add diff as reference
NOTE: This isn't a scientific research. Results may vary between setups.

^ Is that the latest Gentoo stable kernel? LTS is up to 4.1.18 now.

[ChefIronBelly]

^ I pulled (emerge sys-kernel/gentoo-sources and was synced) it a few days ago maybe it updated since. On SID laptop now will check later and thanks for the heads up on LTS 4.1.18.

I was just curious. There is probably very little real difference between 4.1.15 and 4.1.18. It does look like Gentoo is still on 4.1.15-r1.

Do you know if Gentoo does any distro-specific kernel patches? That might be why they are a little behind.

I gave up trying to keep even an LTS kernel completely up to date. They change too fast.

unless you have a shiny new machine I never really understood having the shiniest of shiny kernels.... we are still rocking 2.6.32-5-686-bigmem on some of our machines...all works just fine.

[pidsley]

Do you worry about security patches?

I know what you mean, right now I am happy just to stay up to date with the distro.

*  sys-kernel/gentoo-sources
      Latest version available: 4.1.15-r1
      Latest version installed: 4.1.15-r1
      Description:   Full sources including the Gentoo patchset for the 4.1 kernel tree

[pidsley]

I am quite happy with the 3.2 Wheezy kernel on some of my boxes. It would not give me a 1280x1024 console on one of my newer machines, but the backports 3.14 kernel does that fine. Everywhere else I use an LTS kernel.

The thing I don't understand about LTS though, is that I thought the idea was they were supposed to be "stable" and not need updating as often as mainline. But the LTS kernels seem to get updates just as often, and looking at the diffs they change a lot. Even the old 3.2 and 2.32 kernels get updates.

I don't keep my CRUX boxes (running LTS) up to date all the time though, because I just don't care. Maybe it's a security risk, but oh well.

[wuxmedia]

Do you worry about security patches?

As one of the team USA pointed out - "Above my pay grade"
there weren't all that many, most of the new ones are too new :D
It does happen that machine is due an upgrade.

To be a security risk generally the kernel is attacked from userland (from the three or four priv escalation things i've seen) so I doubt your machines are unsafe.

[pidsley]

Good to know. Thanks wux.

[wuxmedia]

don't quote me on that, I'm hardly infosec guy. :)
It's a weird one we have had boxen pwned before, we DO very much stay on top of our normal security-updates.

[machinebacon]

Do you know if Gentoo does any distro-specific kernel patches?

Yes, they do, however gentoo-sources are minimally patched. There are "git-sources" and "vanilla-sources" (unofficial) if you want to be a step ahead - unpatched - if applicable.
