While playing around with fully featured images, I noticed that
grub-setup takes ages to write the image to disk. It seems that this
is because the disk is opened with O_SYNC, and sectors are written one
at a time. This is terribly silly, so I was going to submit a patch
removing the flag, but I noticed that the flush code that should fsync
after writing the whole image is not actually being called. I traced
it down to here:
grub_err_t
grub_util_biosdisk_flush (struct grub_disk *disk)
{
struct grub_util_biosdisk_data *data = disk->data;
if (disk->dev->id != GRUB_DISK_DEVICE_BIOSDISK_ID)
=> return GRUB_ERR_NONE;
It seems the id is GRUB_DISK_DEVICE_HOSTDISK_ID. What is the
intention of this check and why is it skipping the fsync?
