This is the first time I hear "do not get certified".
I really think that certification is a proof of knowlege.
I know about linux+ and lpi certification, linux+ is very easy, and lpi certification could be very complicated, asking questions (sometimes) that are not relevant for day to day operations (in my oppinion). LPI definitivelly is more difficult, but if you pass it, probably will demostrate that you have solid knoledge in Linux.
Of course, I prefer Red Hat certifications, because is hands on and not just questions.
Now, the certification that you should choose finally also depends of the value of certifications in your country. Maybe, the other people does not know about the certification differences, and certifying one or other will not give you more benefits from the job perspective.
In my country linux is very used for Internet Service Providers and Internet Services. Also, there are some "mission critical" environments running linux, but this is a very small percentage.
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?
