...st often the assumption is made to simulate this parameters with a normal distribution but in the "log-domain" to avoid from negative values to be generated. Since the expected mean  and SD is usually known from the normal domain, using the methods described in the wikipedia article "Arithmetric moments" I generate μand σ and simulate with rlnorm(). At times though the following issue comes up: I have the mean and SD for the parameters available from the normal domain, and the covariance matrix from the normal domain. Then I would like to simulate the values, but to avoid from negativ...

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
