So for Nvidia people. They will likely only have space for 2 maybe 3 UKIs

Gerblesh•6/18/24, 2:29 PM

Are the BT drivers bundled too?

M2OP•6/18/24, 2:29 PM

I don't know. If they are not that is something that can/should be added

MM2 So for Nvidia people. They will likely only have space for 2 maybe 3 UKIs

Gerblesh•6/18/24, 2:30 PM

It depends on how big /boot is right?

M2OP•6/18/24, 2:31 PM

UKIs will go into /boot/EFI unless uefi driver is shipped for ext4

MM2 I don't know. If they are not that is something that can/should be added

M2OP•6/18/24, 2:32 PM

Wait. You will still need the pair data which would need to be done on local system so might as well not include bt driver at build time

Gerblesh•6/18/24, 2:33 PM

Yeah Bluetooth is tricky

MM2 UKIs will go into /boot/EFI unless uefi driver is shipped for ext4

Gerblesh•6/18/24, 2:35 PM

So a UKI with all of the decryption modules + nvidia is around 200mb?

M2OP•6/18/24, 2:36 PM

Yes. Maybe a bit more. And remember that fat32 you lose space

Gerblesh•6/18/24, 2:38 PM

Well

Gerblesh•6/18/24, 2:40 PM

UKIs hopefully will make secureboot actually secure and make systems more reliable, seems like a decent tradeoff to me. Maybe by the time they ship UKIs for Silverblue, NVK will be rock solid compared to the proprietary nvidia driver in performance

MM2 UKIs will go into /boot/EFI unless uefi driver is shipped for ext4

antheas•6/18/24, 2:41 PM

but boot is not efi

antheas•6/18/24, 2:41 PM

unless you do one combined partition, it doesnt make sense to use /boot/EFI

antheas•6/18/24, 2:41 PM

according to the spec they will go to /boot/Linux

Gerblesh•6/18/24, 2:42 PM

Ah that's a bit more space

M2OP•6/18/24, 2:42 PM

But boot is ext4 right now which uefi doesn't have a driver for by default

antheas•6/18/24, 2:42 PM

if we're using a combined partition, users will have to reinstall, so it can be say 4gb

Gerblesh•6/18/24, 2:42 PM

Looks like /boot has 1gb vs /boot/EFI being 600mb

antheas•6/18/24, 2:42 PM

EFI uppercase is the dir inside the efi partition

antheas•6/18/24, 2:43 PM

that the UEFI looks into

antheas•6/18/24, 2:43 PM

so /boot/efi

M2OP•6/18/24, 2:43 PM

Yes. And that's FAT32

antheas•6/18/24, 2:43 PM

then /boot/efi/EFI is where the efis go

antheas•6/18/24, 2:43 PM

or /efi that i think is recommended now

M2OP•6/18/24, 2:43 PM

Yepp.

M2OP•6/18/24, 2:44 PM

/efi/EFI/Linux/*.efi

Wojciech Pawlik•6/18/24, 2:45 PM

Why not simply enlarge /boot/efi/boot/efi?

M2OP•6/18/24, 2:45 PM

Systemd-boot can load uefi drivers. And it has the concept of XBOOTLOADER so things are in place there as well.

But the most ideal thing is if /boot was just one large fat32 partition.

WWojciech Pawlik Why not simply enlarge `/boot/efi`?

M2OP•6/18/24, 2:46 PM

They have. It's now 600 MB. It used to be 200 MB

WWojciech Pawlik Why not simply enlarge `/boot/efi`?

Gerblesh•6/18/24, 2:52 PM

the Bluefin UKIs would likely be larger because of the HWE for decryption support (TPM, FIDO, etc)

Gerblesh•6/18/24, 2:52 PM

there would also be nvidia drivers included in some, which would make the UKIs larger

WWojciech Pawlik Why not simply enlarge `/boot/efi`?

antheas•6/18/24, 3:22 PM

nested mount no bueno

antheas•6/18/24, 3:22 PM

/boot/efi is a partition

antheas•6/18/24, 3:23 PM

according to the spec, either way is fine, with a small nudge to using a single fat32 partition for boot + efi
