Merge pull request #2774 from rear/jsmeix-1024-USB_UEFI_PART_SIZE
|
||
|
|
|
||
|
|
In default.conf increase USB_UEFI_PART_SIZE to 1024 MiB,
|
||
|
|
cf. https://github.com/rear/rear/pull/1205
|
||
|
|
in particular to also make things work by default when additional
|
||
|
|
third-party kernel modules and firmware (e.g. from Nvidia) are used,
|

|
