Interesting, I missed that. I've re-emerged systemd with the gnuefi flag and it "just worked". I do have a UEFI system without systemd that I could try it on.

However, I have been contemplating a new level of (gentoo) install that is less than a default (basic) install with a reduced number of packages. I even have decided to put all the tools (codes, packages etc) onto a separate partition (usb stick) related to compiling. The idea is to build up from scratch what is needed; with a verified DAG of the installed system. Your approach to kernel and boot management is something I'm going to have to experiment with a bit before confidence would allow me to put this idea into my critical path. I am very fascinated by your approach. It does look a wee bit like bootstrapping a LFS or openVZ system. Do you have some resources for recommended reading? Do you use this in a virtualized approach to system management? curiously, James
[gentoo-user] Testing SSD? (Somewhat OT)
Well, I sure haven't had much luck with SSDs. This will be the third one I've lost. On Wednesday I was watching my mythtv frontend when it hardlocked. Last time this happened the 7-year-old rust recordings drive failed. However, all that checked out and I found out I couldn't ssh in to the frontend to kill mythfrontend. I checked the CPU & RAM by booting via USB and it all checked out. I tried booting the SSD and the kernel panicked. After rebooting again, it started, but every command run ended with a segmentation fault. I decided to try flashing the drive's firmware, and that did so successfully. It booted right away after that with no panic, but the frontend decided that it couldn't find the backend any longer. I found this was not true, I (as root) could ping and connect via mysql using remote credentials. After another twenty minutes of fiddling around, I discovered the setUID root bit on /bin/ping had been removed somehow and this was preventing mythtv from finding its backend. At this point I restored from backup and then I discovered after restoring /bin/ping lost it setuid root bit again. After that I gave up (thinking what else has changed on the disk) and yesterday bought a new SSD, this time a SanDisk model. It was cheap and I hope I don't regret this in the future. So my frontend is once again running. That aside, the drive that failed is a Crucial m4. I have done some searching as how to run diagnostics on an SSD. This drive should still have eight or so months of warranty left. These drive did have a bug if they ran longer than 51xx hours but: 9 Power_On_Hours 0x0032 100 100 001Old_age Always - 2382 ...there's only 2382 on this drive. It also accesses all media remotely through the LAN. Currently I'm running shred on the affected SSD. I also could run smartctl on the drive. Do other diagnostic tools even work on SSDs? This is where I'm sort of lost, I've not tried diagnostics on them. I usually send them back for warranty, but this time I'm curious. Dan
[gentoo-user] Project:Installer
>From [1] we have Project:Installer [2] which looks very interesting. However, If I were to create a new gentoo installer, I think I'd leverage ansible and the persistence mode (usb stick) code that LikeWhoa put together, as a basis for the effort. I'd be most curious to read other folk's ideas (strategies) to create a more automated installation semantic for installing gentoo systems. The handbook is fine; in fact it is great. But, many gentoo users that have performed more than a dozen gentoo installs sooner or later get around to their own installations customizations for a wide variety of valid reasons. Ansible would lend itself to expanded and very targeted types of system installs where an accomplished gentoo user could supplement the base install with a collection of specific packages and config settings; imho. Say for example a secure web or mail server, not that it would be the only way to build such a server, but just one specific method a particular author wanted to (share) publish. Surely there are other and better ideas that folks have used or that they are currently contemplating for routine gentoo installs? Maybe some discussion herein could help shape the efforts of [2,3]? Naturally, we should remember Release Engineering and their role as pivotal [3]. [1 and 2] are interesting to read.

Yes Kickstart is very cool [4] and an examination of it, if not outright usage, is a keen idea for discussion. Has anyone actually used kickstart to install gentoo? If so, any links or comments would be keen to read about. James [4] https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/ 5/html/Installation_Guide/ch-kickstart2.html

Re: [gentoo-user] Re: Project:Installer
It appears Kickstart may not necessarily require Anaconda as it is compatible the the Ubuntu installer [1]. While Kickstart itself may or may not be ideal, I think having install parameters in one single file is intriguing. [1] https://help.ubuntu.com/community/KickstartCompatibility J.

[gentoo-user] In the fear of getting hacked (WLAN setup)
Hi, in order to connect my ASUS Memp Pad 7 ME176CX to the internet I need a working WLAN (my DSL router/modem is of the copper area - no Wifi/WLAN). The hardware (an USB dongle) is already there...it needs "only" be configured and setup. The problem I (possibly needless) see is: While I am tinkering and testing the configuration I may setup an open Wifi access point without noticing it in first glance and BANG! get hacked ... in the worst case: unrecognized... What is the "best practice" here? Is there a certain independant configuration, which I can set, which prevents this scenario? Thank you very much in advance for any help! Best regards, Meino PS: If one knows the ASUS Memo Pad 7 ME176CX and knows a way to locally connect this tablet to the internet...this would be a way to go also. I would appreciate any hint in this case (Using Lollipop 5.0).

I would appreciate any hint in this case (Using Lollipop 5.0). If you don't have any daemons running that provide network services (have opened listen ports), you can't get hacked. This is usually a problem for Windows, which by default has a gazillion of services running (NetBIOS, printer/media/filesystem/everything sharing, messaging, remote desktop, etc.) On Gentoo, if *you* didn't set up a service, then nothing is listening on the network.

Briefly:: 'eix -Cc net-wireless' will tell you what the packages in this category do. You either have to purchase a wireless router, or build one with a wireless card, iptables and set up NAT. You'll need some additional software packages from net-wireless. Once you get the wireless device setup, its a good idea to test your wireless network security. net-wireless/airsnort is the grand_daddy Many others exist:: net-wireless/airtraf net-wireless/aircrack-ng is a good start. You can run these from a laptop with a wireless interface. Google for wiki sites or arch linux sites and howto setup and use. hth, James
