This variant has the drawback that the branch which waits for the fstab entry
will wait for the specified time. If the branch which retrieves the passphrase
exits without providing a passphrase (or whatever it does) then the fstab
branch will continue to wait.

Either the fstab branch should be made aware that it waits for crypt, or the
crypt branch terminates the remaining fstab branches.

Looks like crypt handling isnt well designed.
