@mou_bugtracker:matrix.orgmoubut your config mentioned MBR in comments, so it might be different situation for you14:09:13
@not-jack:matrix.orgnot-jackthis is the default config for single disk ext414:10:19
@not-jack:matrix.orgnot-jackso i think we're in the same situation14:11:48
@mou_bugtracker:matrix.orgmouAs i understand logic of the boot process, the important part is decide are you using UEFI. If yes, you have to have GPT partition table (not mbr) and old MBR requirement to have bootloader in first 512K of the drive is no longer reuirement. So this reservation for grub is not needed 14:15:35
@not-jack:matrix.orgnot-jackaha, so it's legacy for backwards compat with grum14:16:46
@not-jack:matrix.orgnot-jack* aha, so it's legacy for backwards compat with grub14:16:48
@mou_bugtracker:matrix.orgmouIt is not grub specific. It is applicable to any bootloader for MBR partitioned drive. All bootloader put their initialization code into first 512K right after partition table14:17:51
@not-jack:matrix.orgnot-jack * aha, so it's legacy for backwards compat with grub MBR 14:19:33
@mou_bugtracker:matrix.orgmouBut i did not refreshed my knowledge in this area for last decade, so i might mix things up. So, if you want to be sure, do additional check.14:19:34
@not-jack:matrix.orgnot-jackthe check will be seeing if i can boot!14:19:50
@mou_bugtracker:matrix.orgmouHere is more in depth explanation of the logic. https://superuser.com/questions/1566558/is-a-boot-sector-considered-to-be-a-partition14:22:28
@not-jack:matrix.orgnot-jackthanks, that helps :)14:26:46

For those using disko for vm’s disk sizes…

I wonder. Are you declaratively setting your vm .qcow2 for example, from the host system? Or from inside the vm.

@not-jack:matrix.orgnot-jackWhen using disko-install, i get no space left on device19:59:11
@not-jack:matrix.orgnot-jackI've tried remounting the store with more space, but that doesn't seem to do anything 20:00:00
@not-jack:matrix.orgnot-jackAnyone have tips? 20:00:07
