    Well, that would be good, actually. Doing the test itself at mount
    time is certainly the simpler approach.

    Is that true for legacy autofs daemons too that distros ship? Because
    those are the ones we'd be fighting..

    Because when I do

    git grep '\<mount[ ]*(' -- '*.[ch]'

    (that's a space and a tab in that pattern) on the autofs-4.1.4 sources
    I downloaded, I don't see a single call to mount. But I do see
    spawning of PATH_MOUNT. And one of them is with "-t", "autofs".

    So at least in the last version of autofs4, it was executing the
    external "mount" program, not using mount(2).
