 |
|
I have been using calculate linux to install gentoo. This works, but their installer isn't perfect. Once you're done it's very easy to switch from their binhost to gentoo repositories, although a binhosted gentoo is very nice too. I have reviewed this elsewhere.
In particular, if you're installing to an old system with no uefi, things get difficult. I believe this is a grub, not a gentoo or calculate problem. The install live cd uses uefi boot, and grub stubbornly refuses to believe that you're doing a legacy install. Uefi has certainly become the default, so installing to mbr from a uefi is more and more of a useless edge case of use to nobody. But I think the same thing could bite straight up gentoo users too.
The calculate installer after correctly installing everything fails with:
| Code: | | Failed to mount efivarfs, installation failed. |
I tried every which way to get it to work, but it just won't. Not a gentoo problem so I won't elaborate. what I did was try to run grub by hand after cl-install exits: # grub-install --target=i386-pc /dev/sdX
That should work, but fails with:
| Code: | Error: Failed to get canonical path of `none'
|
This is a pretty cryptic error, not unheard-of, but definitely a grub error. Grub is looking once again for nonexistent efi partitions of some kind. But after much googling I found the solution. You can override grub's default behavior with:
| Code: | # grub-install --recheck --root-directory=/mnt/test /dev/sdX
|
Of course you have to have mounted your target root directory. Calculate mounts the target disk in a weird place, but I just created /mnt/test and mounted it there too.
That finally worked for me, and I'm on to the next problem. But the post where I found this recommend that you can add "--force" if that didn't work. Since it worked I can't check that.
Cheers,
Jon. |

Virtualised systems are often using a virtualised BIOS.

If you want to install Grub, you either need to chroot into the target system and execute the "grub-install /dev/sda" there or you need to specify the target system with the "--root-directory" option. Because you want Grub from your installed system and not from the live-system. |

| This was a bare metal install, not virtualized. Calculate is especially nice for virtualized, small or one-off systems as you don't have to spend days to compile and maintain them and they're still gentoo. this however, was 100% metal. An old (but still good) system. |
