ubuntu15.04是用systemd的，可以这样做：

cp /lib/systemd/system/serial-getty@.service /lib/systemd/system/serial-getty@ttyS2.service
ln -s /lib/systemd/system/serial-getty@ttyS2.service /etc/systemd/system/getty.target.wants/
再修改/lib/systemd/system/serial-getty@ttyS2.service把里面的“%i.device”改为“%i”

这样解决的：

cp /lib/systemd/system/serial-getty@.service /lib/systemd/system/serial-getty@ttyFIQ0.service
ln -s /lib/systemd/system/serial-getty@ttyFIQ0.service /etc/systemd/system/getty.target.wants/serial-getty@ttyFIQ0.service
再修改/lib/systemd/system/serial-getty@ttyS2.service把里面的“%i.device”改为“%i”
