I put 'Advanced Linux/UNIX system administration experience including LAMP' on my resume if I am looking for a typical IT job for a helpdesk, windows sysadmin etc. If I were looging for *nix work I would go more into detail.
This lets them know you have good experience and if they need any further information they can ask you.
I would also have several version, for example a version for *nix work, retail IT, corporate IT, Helpdesk Tech etc. Just adjust them to the type of job you are looking for.
I have not applied for a job in 8 years but I will see if I can dig mine up somewhere, I did redo them about two years ago when there was talk of them shutting down our location.
