Courtesans and gentlefops! May I direct your attention to:
https://fedoraproject.org/wiki/Anaconda/Features/NoLoader In particular, please note the Scope section, which might also be titled the Big Damn List Of Stuff To Do. The short summary is: Yes, we're really trying to remove loader this time, for real. And it's gonna take some work. So I'm looking for advice and assistance in the following areas: == Boot Option Priorities == Some of these things (ks=, lang=, ip=) are obviously important; some of them are obviously less important (nousb, noprobe), and some of them I'm just not sure if anyone uses them (gdb=, syslog=, wepkey=). If you (or someone you know) depends on any of these things, please give us some information on how and why you use them, so we can make sure things work as expected - and get your help with testing! == Porting to Dracut == Some of these things will probably end up in upstream dracut (e.g. network stuff can go in the 40network module), but a lot of things will end up in our own special dracut module (80anaconda). I'll need some assistance getting all that done for F17, so if you've got some bash skill and want to help with dracut development, this is a perfect place to help make a difference in the quality and stability of the next release! Let me know if you can help, so I have some idea how many people may be involved (and set goals/deadlines appropriately). == General Sanity Checking == Does this plan look sound to everyone? Can we all agree that dropping the stage1 interactive stuff is sane (remember, we'll still have a text-mode installer in the anaconda runtime - just no more dialogs in initrd.img)? Is there anything missing, any improvements you could suggest? Once we've got a finished plan of attack, I might take this to devel-list just to be sure they're all aware (and see if we can solicit further info/assistance).

Once we've got a finished plan of attack, I might take this to devel-list just to be sure they're all aware (and see if we can solicit further info/assistance). Some things that we need to come up with a solution for (where "solution" means either keeping something on our own still called /sbin/loader, or a dracut module, or something else that is run inside the initramfs): 1) Driver update disks require an interactive element at boot time. Doing that once anaconda is not really possible since we may need that driver to get anaconda. A dracut module is fine, but we do need to keep some level of interactive element. NOTE: It does not have to be an ncurses interface, but something interactive so that users do not have to pass long boot options (well, we will probably want that, but we should also have an interactive path). 2) Install method... if we can't find an install source and the user didn't tell us what to use, we prompt in loader. Are we planning to do that via the 80anaconda dracut module? I would say this is important as well. 3) Some sort of minimal interactive network configuration may be required, again so users are not solely restricted to passing boot parameters to dracut. Not sure if this is planned or not. Really, the important one to me is the driver update disk support and retaining that functionality. It's complex enough that we may even want a separate dracut module just for the driver update disk support (79dud?). msivak? -- David Cantrell <dcantrell@redhat.com> Supervisor, Installer Engineering Team Red Hat, Inc. | Westford, MA | EST5EDT _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/anaconda-devel-list |

Why do they require an interactive element? What input is needed? Device name? Filename? Why wouldn't boot args plus default device/filename suffice? e.g.: If you pass 'dd', we'd look for a file named "drivers.img" on a device labeled "RHUPDATES". If you actually need to use different label/filename you could do: 'dd=<device>:<path>'. > 2) Install method... if we can't find an install source and the user > didn't tell us what to use, we prompt in loader. Are we planning to do > that via the 80anaconda dracut module? I would say this is important as > well. Possibly? This prompt would only come up if you don't boot from media - i.e. only on netboot. If you've already set up the netboot server.. couldn't we just use a sensible default, again? Like, if nothing is passed for 'repo=' or 'root=', try a few URLs: http://<server-ip>/<client-ip>/install.img http://<server-ip>/<product>/<arch>/<version>/os/images/install.img Maybe even: http://download.fedoraproject.org/pub/fedora/linux/releases/<version>/Fedora/<arch>/os/images/install.img It's kind of like PXE - if there's no files for the system to PXE boot, you don't get a PXE prompt saying "hey what files do you want to load?". It's already a pretty specialized environment - just set up the server properly and it'll work fine. Or, if you want to make things simpler, you can just cram install.img into the initrd.img. Then you don't need to set up the network etc. to find it. > 3) Some sort of minimal interactive network configuration may be > required, again so users are not solely restricted to passing boot > parameters to dracut. Not sure if this is planned or not. Sure, but again, this is only needed if you're doing netboot. All the simple cases already work (ip={dhcp,dhcp6,auto6}). Most netboot setups seem to automatically set up the boot commandline anyway. Is it easier/necessary to have us maintain a super-limited pre-stage2 interactive UI than to have better docs on setting up netboot environments? > Really, the important one to me is the driver update disk support and > retaining that functionality.

I can definitely understand that this is Required for some Business Use Cases, but I don't fully understand the actual requirements. So yeah, where can we get more info about who uses this, and how, and why, and what they need? -w _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/anaconda-devel-list |

[snip] > Why do they require an interactive element? What input is needed? Device > name? Filename? For me, the interactive element is for diagnosis and recovery from errors. First, I want really good error messages: ones that are good enough to help you _fix_ the problem. For example, not just "No such file or directory" but "Looking for foobar configuration file; cannot open /path/to/the/missing/file because directory /path/to/the/missing does not exist." Then, I want the "last input" loaded into the line editor, with the cursor positioned appropriately, and so that activating the line re-starts the part that failed ("Looking for foobar configuration file" with new pathname), except that <ESC> backs up one step farther, etc. The convenience of retrying the failing action (or backing up step by step) without having to start over from the very beginning, and receiving help such as pre-loading the line editor, is worth a lot for Usability. Being unable to proceed (except by re-booting) is a symptom of failure in the UI. -- _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/anaconda-devel-list |

What is the reason we need these elements interactive in loader? The only thing I can remember is that some vendors ship internal USB flash drives with drivers embedded, and users may or may not want to install those drivers at install time. So looking for and automatically loading all found drivers on driver disks is not ideal in that case. msivak, can you expand on why we need these elements interactive?

Hi,
> msivak, can you expand on why we need these elements interactive? Well, - automatically detected driver discs have to be confirmed before loading (#570053) - we support network method for getting driver discs, so we might need something to let the user set the network up - right now we allow the user to manually select driver update disc or it's image to load. Sources include USB, hard drives, ... That requires some kind of interactivity.

Driver disks may require an interactive element, but can't that just be another screen in anaconda proper? We're already going to have network bring up UI there (as well as cmdline handling in dracut), as well as language and keyboard. It seems to me that we could just toss in another screen at an appropriate place in the UI. Note - likely not an F17 thing. > 2) Install method... if we can't find an install source and the user > didn't tell us what to use, we prompt in loader.

Right now, if we can't find an install source and the user didn't tell us anything, we hit the Fedora mirror list and use the first out of there. askmethod-like functionality is probably required, but should be done in the UI as well. - Chris _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/anaconda-devel-list |

So with install/network sources being handled by dracut, DDs have to go into dracut too..
