Of course :-)
But this gives only names and readonly/readwrite state. 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.
