 ElvishJerricco | I mean it's still cursed | 22:54:03 |
 raitobezarius | I actually don't want to know, the SUSE people told me "yeah I have 30 btrfs snapshots on my micros rn" | 22:54:25 |
| raitobezarius | When I was asking in the room "how many generations people have on their distro in avg?" | 22:54:43 |
| raitobezarius | (spoiler: we are very abnormal but no surprise here) | 22:55:01 |

I think it might be more APFS (volume manager) than APFS (file system) for the really low-level firmware stuff Hmmm you have to have an impl of the FS to load the first stage tho? | 22:55:51 |
| ElvishJerricco | doesn't btrfs handle large numbers of snapshots absolutely terribly or something? | 22:56:06 |
| ElvishJerricco | I mean 30 isn't large even for btrfs IIUC | 22:56:13 |
| ElvishJerricco | but still, the hundreds that nixos people get to would probably be a problem | 22:56:24 |

| raitobezarius | But real talk | 22:56:44 |
| raitobezarius | I want regulation to force DFU like mode for any HW | 22:56:54 |
| raitobezarius | This is the only thing that I miss from the Apple ecosystem | 22:57:08 |
| ElvishJerricco | yea that seems like a good thing | 22:57:10 |
| ElvishJerricco | what exactly is DFU mode, under the hood? | 22:57:30 |

but still, the hundreds that nixos people get to would probably be a problem I got to 1000s so :> | 22:57:39 |
| ElvishJerricco | is it just the firmware booting into a mode that asks for an OS to be handed over somehow? | 22:57:58 |
| raitobezarius | In reply to @elvishjerricco:matrix.org
what exactly is DFU mode, under the hood? Just extra hardware wiring so you can always flash things even if the "main CPU" cannot bring up things for you | 22:58:16 |
| raitobezarius | This is exactly the same thing as those x86 motherboard doing this weird flashing USB port you can always use | 22:58:41 |
| ElvishJerricco | Is anything like BIOS flashback mode that's on basically every PC motherboard now? | 22:58:58 |
| ElvishJerricco | oh | 22:59:03 |
| ElvishJerricco | yea | 22:59:04 |
| ElvishJerricco | matrix delay :P | 22:59:09 |
| raitobezarius | Is it basically on every PC mobo? | 22:59:28 |
| raitobezarius | I only buy high end models so I have a bias | 22:59:34 |
| ElvishJerricco | not the ones you'd find in like HP prebuilts or anything | 22:59:41 |
| ElvishJerricco | but anything you'd buy for DIY has it | 22:59:48 |
| ElvishJerricco | AMD even mandates it on AM5 | 22:59:52 |
| ElvishJerricco | which I guess means they probably put the functionality in the chipset and told everyone not to disable it | 23:01:07 |
| raitobezarius | Very cool @ mandate | 23:01:12 |

Hmmm you have to have an impl of the FS to load the first stage tho? well it looks like iBoot2 is on its own per-OS-container "Preboot" volume and I think that might be a bespoke format rather than an actual APFS file system tree, but don't quote me on that. iBoot1 is read off NOR by SecureROM | 23:05:58 |
