Subject: [PATCH] Skip leading spaces on BLS field values
8631a2
8631a2
The GRUB 2 blscfg command doesn't parse correctly the BLS fields if these
8631a2
have extra spaces before the field values. For example, the following BLS
8631a2
fragment generates a wrong menu entry due using spaces to tabulate values:
8631a2
8631a2
title      Fedora 28 (Twenty Eight)
8631a2
version    4.16.13-300.fc28.x86_64
8631a2
machine-id e5c131dfee3249cbb9891c2641d8e350
8631a2
linux      /vmlinuz-4.16.13-300.fc28.x86_64
8631a2
initrd     /initramfs-4.16.13-300.fc28.x86_64.img
8631a2
options    root=/dev/mapper/fedora-root ro
8631a2
8631a2
Wrong generated menu entry:
8631a2
8631a2
load_video
8631a2
set gfx_payload=keep
8631a2
insmod gzio
8631a2
linux  ($root)    /vmlinuz-4.16.13-300.fc28.x86_64    root=/dev/mapper/fedora-root ro
8631a2
initrd ($root)    /initramfs-4.16.13-300.fc28.x86_64.img
8631a2
8631a2
Correct menu entry after the fix:
8631a2
8631a2
load_video
8631a2
set gfx_payload=keep
8631a2
insmod gzio
8631a2
