I have some ?s already. portalfs works, but I've no experienec with it. umapfs doen't work at the moment because it needs stacking layers to work. > 1) I thought that these babies will allow me to have approx the same as > /proc under linux, since PROCFS in FBSD yields me _pathetic_ stuff. > However, I get /proc/fd dir, with filedescrs (apparently), but there's no > FDESC option enabled in GENERIC kernel. Ideas? /proc is very adequate in doing what its job is: displaying information specific to individual processes and not system-wide kernel specific stuff. The system-wide stuff goes in KERNFS. Also, I believe that in the Linux 2.3.x kernel, /proc has been cleaned up with many parts moved over to /kern where they belong. :) > 2) KERNFS. Is it behaviour the same as of procfs?

You can mount it fine after boot, in fact, you can umount and mount procfs as well, there's just no good reason to be doing so. Here's my line from /etc/fstab: kern /kern kernfs rw 0 0 As far as fdescfs, it is already "mounted" for you at /dev/fd. If you want, you can mount it somewhere else as well. AFAIK, it works fine. > OK, that will be it for now, I guess ;-) > > Thanx for consiring this message. > > ./danfe -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.cslab.vt.edu/~jobaldwi/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
