 Posted: Mon Sep 30, 2024 6:33 am Post subject: [SOLVED] Chrooting while setting up disk encryption |
 |
|
I am using the latest minimal-install USB and following the Full Disk Encryption Guide. This guide, supposedly, integrates well into Gentoo Handbook's workflow. The section on Dracut, however, starts with the warning: | Quote: | | This configuration should be done while chrooted, or on a live system. |
But how exactly should this chrooting be done? Indeed, in the Handbook, chrooting does not come in until much later, and many of the directories (e.g. /mnt/gentoo/proc) do not even exist this early on. Clearly, we are talking about a custom chroot here, different from the one in the Handbook.
Many thanks.

I think the Guide is a little bit confusing, since it tries to handle serveral scenarios at once. Migration, new installation, with different Kernels and Boot loaders.
If you are following the "Installing Gentoo" guide you have to integrate steps 4-6 into the steps 15-18. 3 into 32, 7 into 31 and 2 somewhere between 24 and 44.
Sounds complicated but it isn't: Just follow the order of the installation guide and when you are at partitioning, you have to fallow the partitioning order. When you are at the initramfs stuff you have to fallow the initramfs stuff...
Btw: dracut seems to have trouble with a lot of configurations including encrypted disks. I recommend using UGRD.

| @wanne, thanks for your reply. That was a good advice. Obviously, that document does not have a linear structure and should be followed selectively. Anyways, I finally figured it out. |

These guides are designed to be used alongside the handbook, but the flow from start to finish should be mostly linear. If you're not doing anything advanced, I'd recommend using the rootfs encryption guide:
https://wiki.gentoo.org/wiki/Rootfs_encryption
It's a bit hard to make these guides cover a complete process without greatly summarizing portions of the handbook between 'stage file' and 'configuring the bootloader'. Currently the FDE page is a more advanced page with much more detailed information, where you really have to pick and choose what you want, while the rootfs page is a simpler guide attempting to show necessary steps without being exhaustive.
Encryption information may be added to the handbook at some point, but it requires a lot of consideration to add.
