Re: [Bug-xorriso] ISO installer image: GPT versus MBR partitions

[Thomas Schmitt]

Hi,

Ady Ady gave me a hint about why the EFI partition in Guix 0.16.0 ISO
has 1.4 MB of size, despite grub-mkrescue asks mformat for 2.8 MB.

Obviously Guix uses mtools 4.0.21 (image OEM-ID "MTOO4021") which is one
version before this bug fix:
  "Fixed -f flag for mformat (size is KBytes, rather than sectors)"
  http://lists.gnu.org/archive/html/info-gnu/2018-12/msg00000.html

(Actually this size is quite some waste. Even 1.4 MB is generously
 oversized for the three directories and one or two boot*.efi.)


Have a nice day :)

Thomas
