Custom stuff on netboot machines

Kernel/bootup sequence

The kernel requires several patches to work nicely with aufs. These patches are mostly pretty small, but change from kernel-to-kernel. Googling and looking through the aufs cvs will help a lot. When compiling a new kernel, make sure to read *all* of the aufs docs to find the required patches.

• lhash patch
• put_filp patch
• sec_perm patch

Additionally, when I was compiling aufs, it did not believe that it had NFS branch support. There are some lines in aufs.h that determine if it defines AuNoNfsBrach- comment out the part where it defines it and it will work.

The current (2.6.24ugcs1) kernel also has a one-line patch to fix the vmsplice bug.

There is a lot of custom stuff in /etc/initramfs/ that gets the login machines booting nicely.

e1000

The core2's need Intel's e1000 network drivers. You can find them on Intel's site. After you get clio booted, you can use clio to compile and install these modules so the core2's will boot.

matlab

Matlab R2007b is installed to /opt/matlabR2007b on the netboot images. In /usr/local/bin, matlab, mbuild, mcc, and mex are symlinked to a wrapper script (matlab_wrapper) which prints a message letting users know the license requirements (being a current member of the Caltech community) before running the appropriate program.

Job posting script

The job posting script is in /usr/local/bin/ugcs-jobs. It finds all the files in the drop dir (/afs/ugcs/drop/jobs) newer than ~/.lastlogin, and shows them. It is run through /etc/profile, /etc/zsh/zlogin, or /etc/csh/login.d/ (for the appropriate shell). User documentation is at Website:Job_Posting

mail_forward

Sets up mail forwarding for users. It is a python script in /usr/local/bin/mail_forward

Software no longer installed

libpam-script

This package provides a pam module for running scripts on login/logoff. It was going to be used to do the job posting script, and possibly other things (provide helpful messages when a user is blocked by pam_access?).
