I figured it would happen eventually, but *sniff* bye grub:0 :(
I don't think I will be able to upgrade the bootloader on one of my remotely administrated machines because there's too much risk in causing a no-boot situation...
Sigh.
Oh well.

eccerr0r,
A boot loader is like firmware. Mine was installed in April 2009 and still works today.
Why upgrade?

I think the "lilo" boot loader often is useful.  |

krinn,
all you need is the boot code in very beginning of the drive. Not sure about stage 1.5, don't remember well, but if you back up everything before first partition you should have it. The legacy partition table will be incorrect, but you can overwrite it with fdisk or equivalent.

So, replace the disk and run grub-install. I've done that a few times, the last time was when I replaced the regular disk w/an ssd.
All the stuff to reinstall is under /lib/grub.
Plus even if grub-0 isn't in the portage tree, make it local and keep it around. That's what I've done with grub-static. I have no desire to mess with grub-2.
When I have to update it will be to go full uefi but that's in the future.

Yeah, it should keep working. Probably will need to leave a copy in an overlay so I don't have to just delete grub from world to keep portage happy.

i didn't even have grub-static package
i have just migrate to 64bits with the same disks and the same grub that was from the 32bits installation.
i'll go save it to an overlay now.
lilo has always be a pain for me, you need to run it always after kernel change (while my grub is set to boot vmlinuz and a vmlinuz.old as backup), and if anything goes wrong, grub save you with the "e" key.
where did you get the infos about grub:0 removal btw? |

There was talk of it a few months ago. Devs talking, reached end of life... blah, blah, blah.
Right now, I only have a grub directory (grub-static already removed) and it only has grub-2.02-r3.ebuild and grub-9999.ebuild in it.
Don't know when they cleaned it up.
I keep all my distfiles and portage backed up on a mirrored usb backup system.
I have both grub-0.97 and grub-static-0.97 saved.
ETA: Looks like grub-static was scrubbed sometime during Jan and grub-0.97 sometime during Feb.
grub/grub-static ebuilds and files (for grub) are archived https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-boot/

I probably should just migrate everything to grub2 anyway, but what works...works. If the machine's locked in a room and 2000 miles away, not much you can do to exploit it if there are bugs...
I just have a mixture of grub:0 an grub:2 machines. I don't mind grub:2 at all, just that it's downtime if I get the config wrong. Question is when I test it. Do I test now and take the downtime now, or do I wait until power goes out and it doesn't come up then...

FYI, you don't have to use the "automatic" tools. You can do everything manually like before with minor syntax changes to the configuration file.
| Code: | timeout=5
default=1
menuentry "Text you want to display" {
set root=<...>
linux <...>
initrd <...>
}
menuentry <...> |

Thanks, pjp, simple enough.
The other thing I want is a completely static binary, similar to busybox, I don't want to depend on any dynamic lib.
I know grub-2 has a static flag, but in looking at it, it doesn't seem to require all things to be statically built in. I need to pull the tarball and look at it in depth.

| For anyone who wants to avoid both Grub and Lilo, I suggest syslinux. It can boot both BIOS and UEFI modes, and has a configuration file to let you configure a list of kernels for the user to choose from. Each entry can have its own command line. |

I can't agree enough. Syslinux is wonderfully lightweight and easy to configure. I switched to it when Grub 2 came out and haven't looked back. |

My value in grub comes from its "e" key power ; i find grub configuration easy to use because i'm use to it, but it's true at first the hd0 (range start at 0) and partition (range start at 1) syntax can mislead everyone.
lilo was easier to handle.
But whatever is the diffulty of the configuration or syntax, i just cannot live without that "edit" functionality ; it has saved me so many times and i'm so lazy to use an usb key/livecd |

I also stick with grub because of the CLI that it presents with editing. Sometimes just a small error can be fixed and you get a bootable system once more. Also due to its filesystem drivers, you can choose kernel and initramfs images that were not initially preselected by lilo, even on esoteric filesystems like xfs, jfs, reiserfs, etc. if it were not moved to the right place prior to restart. There's no "ls" functionality but the tab completion effectively will get you file and directory lists from grub directly.
It's saved me many times from reaching for a rescue boot image. And even from rescue images with grub I can get a damaged system to boot on its own with the system's incorrectly positioned kernel or command line options too, not required to use a rescue image kernel.
Just that grub:0 was still working just fine, even if grub2 works equally as well :(

| Glad it works for you guys. All my computers have a DVD drive. The oldest is IDE! I keep a sysrescuecd CD in them at all times, just removing if I want to play a DVD which is rarely. I don't know if it's legal, but I've ripped some of my DVD's for personal use only. I don't sell or give the mpeg's away. When I've paid money for a DVD (or tape back in the day), I don't want to watch a commercial first. |

I guess some of my machines don't have media other than hard drives, mostly because their cases don't have space for an optical drive. But sometimes grub isn't enough still when grub gets corrupted (oh no why can't I emerge grub:0 again?), alas, time to connect a USB optical drive.
My offtopic 2 cents: ripping DVD/CD should be legal as long as:
1. You don't give away or sell the mpeg/mp3. No anonymous/public viewing, etc. Only for personal use.
2. You don't give away or sell the original CD/DVD. Have them ready for re-extraction if someone asks. Don't put them offsite, at most keep in attic or basement. I notice a lot of people donating their DVD/CDs, I would think when donating the rights to view/listen to the media are donated as well - whatever was ripped and kept is now illegal.

I'm here to tell you that syslinux does have command-line editing. The keystroke to start editing a command line is not 'e', as in grub, but <tab>. Once in editing mode, <enter> boots with the edited command line while <esc> cancels input and returns to the boot menu.
I'm not just telling you that from memory or from a simple trusting of the documentation--I tried it just now. |

Where can I find more about syslinux? I went lilo because I couldn't find Grub when installing this new pc. Just because I always have issues because this silly thing always lists the HD's in a different order when starting from the minimal install dvd or when starting from the fresh install. With the command line at least I could try a few things until it started and then edit it in. But lilo is soo slow to boot... takes minutes.
