Last time I had a problem like this I spent a lot of time googling about
ulimit/setting_limits/etc and found _nothing_ worth mentioning. This time I
run "ulimit -v unlimited", but the question is who put the former values
there?  Some hard-coded default? I couldn't find anything in init scripts nor
in bash rc files. I know that on logout the value is lost (I had to run ulimit
again on chrooting). What is the appropriate file to put "ulimit -v unlimited"
in? Perhaps ~/.bash_profile? And how can root set different hard limits for
different users? Maybe some bash guru will step in?:)
