Many of GRUB's utilities don't check anywhere near all the possible write errors. For example, if grub-install runs out of space when copying a file, it won't notice. There were missing checks for the return values of write, fflush, fsync, and close (or the equivalents on other OSes), all of which must be checked. I tried to be consistent with the existing logging practices of the various hostdisk implementations, but they weren't entirely consistent to start with so I used my judgement. The result at least looks reasonable on GNU/Linux when I provoke a write error: Installing for x86_64-efi platform. grub-install: error: cannot copy `/usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed' to `/boot/efi/EFI/debian/grubx64.efi': No space left on device. There are more missing checks in other utilities, but this should fix the most critical ones. Fixes Debian bug #922741.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
