-====== First Year Accounts ======
-Students in first year do not get an EECS account.  Instead, they login to workstations in certain labs as user //user// with no password.  A home directory on each local machine is configured for the user (/home/user).  The home directory is cleaned between login sessions of all user modified files.  The changed files are archived, and accessible to faculty and lab technicians for a limited time.
-The //user// account does not have access to printing or e-mail.  It does have access to all the software available to regular EECS accounts because these machines mount the standard /eecs hierarchy from our file server.  Most software required by first year courses has been locally cached on these machines in order to ensure the highest performance.
-====== Submit ======
-Students with EECS accounts use either command line submit, or web submit to submit assignment submissions.  Students logged in as //user// can only use web submit, and must authenticate using their Passport York account.
-====== Home Directory ======
-The home directory for user //user// is local to each machine (/home/user).  It is a mirror of /eecs/local/pkg/user, available from all EECS tech supported systems.  Changes made to the master copy of the home directory will be automatically synced to the local workstations.
-====== Labtest ======
-First year courses use labtest.  Labtest works with the //user// account but there are a few exceptions to be aware of:
-  * Changed files are **not** synced to /eecs/ltsave like in regular labtest mode.
-  * The "unsubmit" feature of labtest is unavailable.
-  * If users switch machines during labtest, you or your TAs will be unable to transfer their files between machines.
-  * Any power failure during labtest will result in all the home directories being reset after the power failure.  Faculty and lab technicians can get a copy of these files, but it will be very difficult to retrieve them back to individual machines in a timely fashion.
-====== Backups ======
-Each time user //user// logs out, files that the user has changed that are greater than 1 byte and less than or equal to 25 MB are archived into /local/user-backup into a directory named MMDDYYYY-HHMMSS.  That is, two digit month, two digit day, four digit year, then two digit hour, two digit minute, and two digit seconds.   Only faculty and lab technicians can access these archives.  Monitors, grads, and TAs cannot access this directory directly.  Local backups will not occur for EECS accounts.
-If you are a Faculty member, and logged into a workstation that supports //user// login, you can access these backups in the /local/user-backup directory.  Lab technicians  must first use the "bu labtech" command to become the //labtech// user.
-After changing into the /local/user-backup directory, do an "ls" to see the available archives.  Change into the appropriate dated directory, and retrieve the files.  The last directory in the list will be the latest backup.  Up to 40 backups will be kept from the last 40 logins.  After that, the oldest backups will be automatically removed.
-Faculty and lab technicians can also SSH to lab workstations, and access each machines archives in /local/user-backup.  Remote access to machines is restricted when the machine is in labtest mode.
-====== Recovery/Restore ======
-From time to time, the graphical interface on a machine may hang, and the user will not be able to continue working.  For example, the mouse cursor may move, but nothing can be clicked.  In these cases, faculty, lab technicians, monitors, and grad students can carry out a procedure to restore the user files and allow the user to continue.
-Follow these steps:
-  - Reboot the system.
-  - Log back in as user //user//.  **The user won't see any of their previous files.**
-  - Open a terminal window by right-clicking on the desktop, and choosing "Open Terminal".
-  - Login to your personal EECS account:<code>
-% su gayan
-Password: *******
-</code>
-  - Run the "restoreuser" command.
-  - Select the backup you wish to restore.  Option 1 will be the latest backup.
-  - The files will be restored into the //user// home directory.
-  - Exit your account:<code>
-% exit
-</code>
-  - Now the user can continue working.
