It was not for me. It seems that for most newbies, it is fairly straight forward and painless. Depending on your hardware and installation choices, it typically takes 0.5 h to 2.0 hours. [Expect longer or possible problems for slow systems with very restricted memory--it took a whole night to install RH6.0 on my 486-33 MHz with 8 MB memory, the system pausing for 5 minutes at a time appearing to do nothing, yet it installed ok.] Upgrades from previous installations take longer and tend to be more problematic.
However, some newbies reported that the installation was a "total nightmare" to them (hardware problems? lack of experience?). If you encounter problems, my advice would be to install a plain-vanilla system, without struggling with the highest resolution on your fancy video card or other bleeding-edge hardware peripherials which you might have. Anything can be added/configured later, after you get more understanding of how things work on your system. Even a re-install is always an option for a newbie (it seems Linux gurus think it is a shame to ever re-install Linux). It seems that many newbies have problems because they specify too high screen resolutions (which may be not supported or supported only with some extra tune-up). Again, it may not be wise to break your whole installation for support of a single device--the support can be added/tuned-up later.[an error occurred while processing this directive]
