 |

[Moderator note: this post and the first several responses were originally attached to the solved 2011 topic problems with virtualbox 4.0 headless VRDE RDP [SOLVED]. -Hu]
Good news to report.
All the machines are all current and happy. emerge -UD --newuse @world executes on all of them cleanly without any updates pending.
Except for one thing. Grub. I like, and want to keep, sys-boot/grub-0.97. The only complaint from emerge is:
| Code: |
>>> package: sys-libs/ncurses-6.1_p20190609
* - /usr/lib32/libncurses.so.6
* - /usr/lib32/libncurses.so.6.1
* used by /sbin/grub (sys-boot/grub-0.97-r18)
* - /usr/lib32/libtinfo.so.6
* - /usr/lib32/libtinfo.so.6.1
|
Now, I know that the part of grub that uses the curses library is doing so before Gentoo boots up, so you'd think it would be a statically linked executable, and wouldn't need the shared curses libraries.
I guess the next step is to set up a private overlay that only contains this version of grub (and other versions of packages that might end up there).
Anyone have any good pointers to some documentation or guides that I can read up on this?
Thanks to everyone for all the help that I've received. |

I think you are incorrect here. The bootloader portion of grub runs before root is mounted, so if it depended on dynamic linking, it couldn't start. I think /sbin/grub is a Linux program used as part of preparing/configuring the bootloader. I switched off grub (and not to grub2) long ago, so I don't have a local copy to check, and my search results are just finding people who had problems using grub. | eohrnberger wrote: | | I guess the next step is to set up a private overlay that only contains this version of grub (and other versions of packages that might end up there). |
That or switch to a different bootloader. I like syslinux. |

Yeah, I know it's an old thread, but didn't I promise to follow up here?

Well, that was exactly what I was saying. Maybe it didn't come through clearly. <*shrug*>
On boot, the grub draws a nice screen image, I'm guessing it's using curses for that. The rest of grub, if I'm not mistaken, are all CLI programs, and have no need for curses.

Yeah, not sure which way I'm going to go. A really skinnied down grub.cfg for grub 2 isn't all that bad. I may end up going that way. |

You are not the original poster of the thread. That poster never indicated a follow-up would be forthcoming. Thus, I don't see any indication in this thread that you promised to follow up in this thread. | eohrnberger wrote: | Well, that was exactly what I was saying.

You can guess that, but I'm pretty sure your guess would be wrong. Curses needs a working kernel, and there isn't one that early. The pre-kernel grub uses its own, curses-independent mechanism for drawing. |

So then what's the dependency between grub and curses?
Oh well, I'll stop posting here then. |

I got curious and looked, and this seems correct. /sbin/grub appears to be an internal program called by GRUB Legacy's grub-install. |

Yeah, that makes sense because the 'grub' command loads the grub shell, which clears the screen, has screen character highlights and such.
Cheers! |

I have grubb-0.97-r14 , r15, and r16 in local overlay, but you should be able to find it in the portage attic.
I also have the patches: | Code: | grub # ls -lh files
total 16K
-rw-r--r-- 1 portage portage 1.1K Mar 7 2016 gfxpayload.patch
-rw-r--r-- 1 portage portage 591 Aug 8 2015 grub.conf.gentoo
-rw-r--r-- 1 portage portage 1.6K Dec 15 2015 grub-legacy-0.97-Add-esp-to-list-of-clobbered-registers.patch
-rw-r--r-- 1 portage portage 799 Dec 18 2015 grub-legacy-0.97-ncurses-pkgconfig.patch
|
which might be small enough to pastebin.
The main distfile is rather too big to pastebin: | Code: | grub # ls -lh /usr/portage/distfiles/grub-0.97.tar.gz
-rw-r--r-- 1 portage portage 950K Jun 28 2018 /usr/portage/distfiles/grub-0.97.tar.gz |
But you might find it on the web.
I still use it on motherboards that do not have EFI. On newer boards I use reFind from portage.
EDIT:
newest EAPI is 5, so I may have to update it soon. Right now I'm using unmodified Gentoo ebuilds. |

I think I have all the files needed for putting together grub-0.97 with the gentoo patches-1.15. |
