 Posted: Tue Sep 05, 2006 11:07 am Post subject: Recovering /var/db ??? |
 |
|
For whatever reason Gentoo decided to hang during shutdown (not reboot for some reason though) and I had to hard reset... Well, long story short the entire /var directory is hosed. To its credit Gentoo was able to boot fine missing /var (I had to re-create a couple of subdirs), but since I lost /var/db/pkg portage has no idea what packages are installed.
I think I know the answer to this (i.e. re-install from scratch), but is there any way I can somehow rebuild /var/db/? Thus far I've just been re-emerging everything, but of course I can't remember all the packages that were installed and some are starting to break because portage has no idea what dependencies are installed. |

Did you try a revdep-rebuild? or the dep tool by ecatmur?
They won't catch 100% of everything, but it might get you close enough to not have to reinstall from scratch. |

Thanks, I'll give those a try... I wasn't sure if they were the sort of tools that could do more harm than good, but I suppose what do I have to lose..? |

| They won't help. The only thing that will rebuild you /var/db/pkg is emerge -e world. |

Which also won't work as world resides in /var/lib/portage/world
fearofcarpet you are screwed, no doubt about that. The only other solution than reinstall from scratch that comes to my mind would be to emerge -e system and then try to figure out yourself, which other software you have installed on that machine and reinstall that as well. But this can be a painful thing to do and you should really consider to reinstall from scratch after you did a backup of /home and /etc.

Ouch, you are right. Missed the part where ALL of /var was lost... |
