Bellow is a little info from /usr/src/linux/Documentation/proc.txt, I have not try say that FreeBSD need /proc like this, but, FreeBSD need documentation like this: 3 Reading and modifying kernel parameters A very interesting part of /proc is the directory /proc/sys. This not only provides information, it also allows you to change parameters within the kernel. Be very careful when trying this. You can optimize .... 3.2 /proc/fs - File system data This subdirectory contains specific file system, file handle, inode, dentry and quota information. Currently, these files are in /proc/sys/fs: dentry-state Status of the directory cache. Since directory entries are dynamically allocated and deallocated, this file gives information about the current status. It holds six values, in which the last two are not used and are always zero. The other four mean: nr_dentry Seems to be zero all the time nr_unused Number of unused cache entries age_limit Age in seconds after the entry may be reclaimed, when memory is short want_pages internal ... and so on With FreeBSD "man 8 sysctl" gives kern.maxvnodes integer yes kern.maxproc integer no kern.maxprocperuid integer yes kern.maxfiles integer yes etc. By contrast most of FreeBSD documentation is better than GNU/Linux equivalents. But Linux, kernel :-), part of documentation is better on GNU/Linux, at least it is more searchable. -- Igor Roboul, Unix System Administrator & Programmer @ sanatorium "Raduga", Sochi, Russia http://www.brainbench.com/transcript.jsp?pid=304744 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
