How 'bout that! And you know, a few people have even told me they think
that on my goods days I can even manage to walk and chew gum at the same

Again, you confirm my original premise - that much of the discussion
under this thread implicitly assumed linux/unix experts are the ones
installing the system. You know! That assumption stated in the lead
in paragraph in the prior message which you elected to delete in
drafting your reply. The one that read,
"Discussion in this thread frequently reflected an unwarranted,
underlying assumption. Namely, that linux/unix experts are intalling
the OS, know how the system will be used, and act immediately after
installation to reset default installation resource limits to
appropriate levels. It is obvious to me from thread discussion that that
assumption is invalid. "

Your statement reflects uni-dimensional perception of costs and
benefits. Linux is "free" product to the non-expert only in the sense
that it may be obtained without any explicit cash outlay for the
acquisition. But, there are boatloads of implicit costs the non-expert
bears in attempting to install and use a linux operating system. Time
spent on the endeavor is NOT a free good. The opportunity cost of the
time spent by linux newcomers lacking prior familiarity with
linuxeese/unixeese can be quite high as can be the payback to Red Hat
for the expense it incurrs in lowering the acquisition cost of Red
Hat/Fedora linux distributions and this user forum.

It is documented for those who know the word exists, yes. That is, it
is documented for the subset of linux users who have more than passing
familiatity with unix/linux commands and operating system
characteristics. And, the particular default resource allocation
parameters specific to Fedora Core releases were known only to its
kernel developers and those users expert enough in linuxeese to use the
ulimit command.
