How many night shifts you're going to have depends IMO on your own ability and your company. Example: at our company we don't do any real night shifts, but only on-call (always three people), since we don't have a single point of failure. If an application has to be updated, only one of three servers for that job is (planned) down at the same time, so upgrades can be done during business hours.
As for the ability part: if you're really really good you can set up your systems in a way that they can handle anything but the most severe cases by themselves, even if it just means limping until normal office hours.
But in the end the decision is pretty simple: the deviation of your work hours from the usual is directly proportional to the deviation of complexity of your problems from the usual (read: the more complex the problems the higher the probability that they happen when you're not in the office)

Any of the four pieces of information can be specified on the command line. If no information is given on the command line, chfn enters
interactive mode.
INTERACTIVE MODE
In interactive mode, chfn will prompt for each field. At a prompt, you can enter the new information, or just press return to leave the
