 Posted: Thu Oct 31, 2013 11:59 am Post subject: [SOLVED] I don't understand these portage messages |
 |
|
I installed Gentoo on my laptop in March of this year, "for practice". Then I installed Gentoo on my main computer, which I've been using ever since. I update the main computer regularly (maybe once a month). So far I've always managed to make sense of the sometimes cryptic "after installation" messages.
Last night I updated the laptop for the first time since the initial installation. The laptop essentially has nothing installed except the basic installation, plus leafpad, urxvt, spacefm, and alsa/vlc. Previously it had some qt/kde stuff (dolphin, rekonq, konsole), but I uninstalled every scrap of kde/qt I could find before updating. It was a completely kitless install, so there was no kit stuff to uninstall.
144 packages were updated. There were 23 messages and I couldn't understand some of them, so I'm leaving the laptop running until I can figure them out. Please bear with me, I know these must seem like stupid questions to most of you.

What does this accomplish or not accomplish, depending on whether one does it or doesn't do it, whatever "it" is?

I don't want to use grub2. What do I need to do?
There's more I don't understand, but that's enough to get started! Thanks in advance for any assistance.

Some of it tools need it such that instead of the tool having to ask you to rebuild the database as root, it runs right away; `qgrep ...` for example does this.
So, rebuilding the database upon sync makes you have it ready when you need it for the tool. So, postsync.d/q-reinitialize does what the name says, it makes q ready for you after syncing.

I don't have GRUB Legacy anymore, but this seems to tell two things; (1) is that it will try to mount and install for you unless you `export DONT_MOUNT_BOOT=1` before running emerge (or put it in package.env), (2) seems to say a lot for what is kind of equal to "you must update the grub on your boot by reading the handbook and documentation and doing the grub steps again; if you don't, mismatching versions could break boot".

`emerge -c sys-boot/grub:2` will unmerge any version in SLOT 2 of sys-boot/grub; so, it will unmerge any version of grub2. Because it is -c and not -C, it will also unmerge any dependencies of it which no other packages of your system need anymore. |

| Hmm, thank you very much for replying. However, I think I have messed up the laptop to the point of needing a reinstall. I accidentally upgraded gcc and then accidentally removed the previous gcc. Now nothing will build. |

| Is there a way I can chroot into the installation and fix this mess that I stupidly got myself into? |

This post enabled me to solve the gcc problem: https://forums.gentoo.org/viewtopic-t-948028-start-0.html
The problem was I didn't select the new gcc, so nothing new would build.
I don't think I'm using grub2, because I restarted the laptop with no problems. I will mark this as solved. |

If needed, see https://wiki.gentoo.org/wiki/Chroot for reference; it boils down to doing the mount & chroot steps from the handbook again. |

Though grub2 was emerged, it won't actually be active unless you install it. Guide here, if you so desire: http://www.gentoo.org/doc/en/grub2-migration.xml
It up to you to switch or not. If you decide not to switch, you'll want to request grub legacy, so it doesn't get unmerged if you do a depclean.
