We are having a problem at our site in that we would like to increase the number of files that a user can have open at one time from 20 files to 30 files. I found where to change it in param.h and I've remade the kernel after changing it there, but when we reboot with the new kernel, several things don't work correctly. If you do a 'ps', you get nothing except the header line. Also, it shows the 'init' process having some huge amount of cpu time. Is there any other place that needs to be changed, other than the value in 'param.h'. Please send mail as our site has had problems getting the news. Thank you.

This is the purpose of the 'make depend' in most of the Makefiles in /usr/src/*. You should be able to get a list of the files you'll have to recompile with the command 'grep param.h /usr/src/*/Makefile'. Fantisizing, it may be useful (and sobering) to have a daemon with a full table of dependicies send the system administrator mail reminding him of the work ahead of him whenever he/she touches system headers.
