What's the file-system structure going to be on the new machines?

Local partitions:

All machines should have a /, /var, /usr, and swap partition. I recommend the following space allocations:

• / - 100MB (allow a few different kernels to be there)
• /var - 100MB - 256MB
• swap - 2.5 * memory - That means 320MB on most of the newer machines.
• /usr - the rest of the first disc.

If the machine has two discs, use the second one as a /playpen.

Mounting file servers:

All nfs mounts should be in /net/<machine_name>/<file-system>. The intent here is to be consistent with the way the department mounts file-systems (especially on buzzard). This is important if you are going to work in your FreeBSD home directory (/net/buzzard/dirt) from the departmental machines because your symbolic links to things like /net/buzzard/smithfd will work both on FreeBSD and on departmental machines. Also, it's handy to include the machine name and file-system in the mount point for informational purposes. For example, most machines will probably have the following systems mounted:

• /net/buzzard/dirt
• /net/buzzard/smithfd
• /net/buzzard/dirt-bulk
• /net/buzzard/playpen
• /net/buzzard/dirt-playpen
• /net/buzzard/jeffay2
• /net/tyagi137/usr

Note:This structure should also lend itself to easy use of the automounter if anyone wants to explore that option.

Standard symbolic links:

All systems will use symbolic links into the file-systems mounted under /net/ for things like the home directory, source for the kernel and other tools, standard tools, etc. Here's a list of some of the links:

• /usr/home -> /net/buzzard/dirt
• /usr/src -> /net/tyagi137/src
• /usr/dirt -> /net/tyagi137/usr/dirt

Standard DiRT directories and conventions:

I recommend using a set of directories under /usr/dirt or /usr/src for any tools we write ourselves or information or configuration files. These directories will be accessible on all machines and should survive upgrades, etc. (where /usr/local might not). Note:Standard package installs are not what I'm thinking about here. Installing packages on multiple machines is addressed elsewhere. I'm concerned with tools we maintain (and, thus, may change frequently). I'd recommend:

• /usr/dirt/bin -> scripts and tools (xplot-dirt, tcptrace-dirt, addusers, etc.)
• /usr/dirt/lib -> libraries we maintain ( xplot_lib??)
• /usr/dirt/lib/perl -> perl libraries we maintain ( dirt.pl?? )
• /usr/dirt/dist -> files that we want to distribute to other machines to maintain consistency. For example, copies of:
  • /etc/hosts
  • /etc/groups
• /usr/dirt/packages - package files for distribution (e.g. emacs-19.34b.tgz). rsh pkg_add package_name comes in handy.
