On Tuesday, code-analysis software maker Coverity announced that its automated bug finding tool had analyzed the community-built operating system FreeBSD and flagged 306 potential software flaws, or about one issue for every 4,000 lines of code. The low number of flaws found by the system underscores that FreeBSD's manual auditing by project members has reduced the vulnerabilities in the operating system, said Seth Hallem, CEO of Coverity.

"The recent 2.6 Linux production kernel now shipping in
operating system products from Novell and other major Linux software companies contains 985 bugs in 5.7 million lines of code, well below the industry average for commercial enterprise software."
FreeBSD seems to have about 1.2 million lines of code (306 potential flaws * 4000 lines/flaw). An example of code bloat in Linux (which is just a kernel, compared to the full operating system that is FreeBSD)?
Member since:"Coverity found 306 software defects in FreeBSD's 1.2 million lines of code, or an average of 0.25 defects per 1,000 lines of code. In a December 2004 study of the Linux kernel, Coverity found 985 software defects in 5.7 million lines of code, or an average of 0.17 defects per 1,000 lines of code."
"We want to emphasize that the Linux code base is larger and has more driver support than FreeBSD."

According to Coverity, there is about "0.17 bugs per thousand lines of code" in Linux (http://lwn.net/Articles/115530/) vs. 0.25 bugs per thousand lines of code in FreeBSD...
