Request to blacklist floppy for images on Azure

[Joseph Salisbury]

After booting, there's an error message in dmesg:
"blk_update_request: I/O error, dev fd0, sector 0"

There’s no point in having a floppy driver, and the “I/O error dev fd0 sector 0” messages are distracting where there is no real issue.

Blacklisting floppy can avoid this error.

Adding a file into the /etc/modprobe.d directory is one approach. You can name the file whatever you want that ends with .conf, and the contents just need to be “blacklist floppy”. Using a separate file means you don’t have to edit any existing files, so it’s easy to update an existing image.

However, another approach might be needed if the floppy driver is initramfs.
