@gwgwgwgw:matrix.orggwgwgwgwOkay, so if I ever accidentally manually created a partition of that exact size, it *might* get written over the uboot image?20:41:46
@gwgwgwgw:matrix.orggwgwgwgwWell, it probably would if the other partitions spanned the whole rest of the disk20:43:17
@gwgwgwgw:matrix.orggwgwgwgwJust wanna make sure my mental model of this thing is accurate20:43:33
@dgilmore:libera.chatdgilmoreRight, there is a chance you could overwrite it, but you would have to go take some actions 21:04:12
@adamwill:fedora.imadamwugh, so i reflashed my jetson with f36's uboot, still no dice. it refuses to boot from my microsd card. it did this fine two days ago since when i have changed nothing. what the hell21:17:06
@dgilmore:libera.chatdgilmore adamw: what's the output? 21:19:58
@adamwill:fedora.imadamw dgilmore: https://paste.centos.org/view/cba521b9 21:21:17
@adamwill:fedora.imadamwthe card is fine, if i attach it to a regular system it is read and mounted.21:21:38
@gwgwgwgw:matrix.orggwgwgwgw dgilmore: is that a common thing in ARM SBCs? That they just suck uboot off a non-partitioned space on disk? 21:51:50
@dgilmore:libera.chatdgilmoreyes it is 21:57:56
@adamwill:fedora.imadamwthat's also how BIOS PCs work, of course...21:59:43
@dgilmore:libera.chatdgilmore gwgwgwgw: the Raspberry Pi is one of the few that doesn't many can pull system firmware from SPI, thougha lot of SBC makes do not go to the expense of adding SPI 22:00:11
@gwgwgwgw:matrix.orggwgwgwgw adamw: do BIOS PCs not have the ability to read partitions? I was under the impression they did, but never really had to check 22:38:54
@gwgwgwgw:matrix.orggwgwgwgwI always thought BIOS PCs read the boot partition to launch grub, then grub launches the rest of the OS22:39:57
@adamwill:fedora.imadamw no, they read the boot sector. (which, in grub's case, then loads in an intermediate stage of grub from unpartitioned space, which then reads the boot partition) 22:40:37
@gwgwgwgw:matrix.orggwgwgwgwObviously Haven't spent enough hours looking at hex edits of disks22:42:12
@adamwill:fedora.imadamwtechnically stage 1 could load stage 2 from a partition, but it doesn't have much space to do a filesystem implementation so this isn't usually what happens.22:45:03
@adamwill:fedora.imadamwsee https://wiki.osdev.org/Bootloader_FAQ and https://wiki.osdev.org/Boot_Sequence , anyhow.22:45:17
@jlinton:libera.chatjlintonanyone else notice this?23:25:29
@jlinton:libera.chatjlinton [anaconda root@fedora sysroot]# find . -name "*.rpm" |wc -l 23:25:48
@jlinton:libera.chatjlinton can't believe I didn't see that before, its only after the 1000th time installing this month old version of F37 did I notice that it said it was downloading 666 packages. 23:26:34
@jlinton:libera.chatjlinton(mostly default server install)23:26:51
@dgilmore:libera.chatdgilmoreNeed to add a dep on something to make it 66723:42:15

@hrw:libera.chathrw adamw: isn't it that boot sector grub reads from 'those sectors/blocks which keep rest of grub' (declared at 'install-grub /dev/sda' phase)? Which on GPT partitioned storage is often place on no filesystem partition type 0xfe02 (bios boot partition). 07:56:03
@javierm:libera.chatjavierm hrw: yes, I think adamw is mentioning how it works for MBR which is the default for legacy BIOS installs in Fedora 08:07:43
