Lennart,

I noticed this a while back, too. I don't believe you can currently. As a
workaround, you can use debugfs:

    debugfs -w -R 'set_super_value mount_opts opt1,opt2,opt3' <dev>

Note that when printing superblock info, the e2fsprogs tools call the bit-based
default mount options "Default mount options" and the string-based default mount
options "Mount options".
