According to the man page, /etc/mtab is actually generated by `mount`,
not the kernel. So, it might be possible to "improve" the output of df
by patching mount so that /etc/mtab looks more like /etc/fstab or
/proc/mounts. (AFAIK df gets its list of devices from /etc/mtab, via
getmntent(3).)

Hmm :)
