Subject: GRMLBASE/45-grub-images: calculate real disk size of bootx64.efi
X-Git-Tag: v0.19.4~3
X-Git-Url: https://git.grml.org/?p=grml-live.git;a=commitdiff_plain;h=06021ae3a93b2e3a21058fdbf4d69d646dd83312

GRMLBASE/45-grub-images: calculate real disk size of bootx64.efi

Fixes case where size of file is mis-detected due to transparent
compression, resulting in "disk full" error when running 45-grub-images

Thanks: Andras Korn for the patch
