Personally, I was getting a little involved in the Linux Certification process. It really would be a great cert to have as part of a certification portfolio. Employers always want to know if you know Linux.
I noticed that Novell offers a CNA or CNE or something for their Suse product. The CNA was always the most respected network certification years ago. I think being Suse certified by Novell would be a real feather in the cap.
It depends on your strategy and planning. Either you stick with one type of certification from the same vendor or you want to be more independent.
The stick-with-cert-vendor strategy: take LPI certification (about 6-7 exams till the advanced level, every 2 exams you get certificate --> fundamental, intermediate, enterprise) or RHCE (total about 6-7 exams, after the first 3-4 exams you get RHCA I think) or Novell Linux Certification (Novell Linux Professional and Novell Linux Engineer). In this field, RHCE is the most respected and most difficult one.
The i-am-not-so-sure strategy: take CompTIA Linux+ (1 exam) than you can decide later if Linux the right one for you to take certification and do the stick-with-cert-vendor strategy
