Major Changes
With the one-account system moving into place, several things are changing in the way the system is setup:
- no more course accounts
- initialed accounts based on shortid
- identities instead of groups
- a new fsh
These student accounts were created at the start of the semester, had a small quota (typically 1-2 megs), used fsh as the login shell and were destroyed at the end of the semester. A student might have to juggle two or three accounts in a semester, and would have to somehow backup data between semesters. The accounts themselves were in a class group (for example, ``cs031''), and this along with the account name gave permissions to login to certain machines, handin assignments, etc.
Under the new system, each student will be given one account when they take their first CS class. The login name will be their CIS shortid (which is unique), and this account will be kept as long as they are in the department. As is the current practice, all accounts will have a base limit of 10 megs, but depending on involvement in classes or projects, this could increase.
Instead of determining these disk space changes, as well as handin permissions and access rights on account names or UNIX groups, each account will also have a certain number of identities. These are explained in more detail later, but they act to modify accounts.
Under the old system, course accounts used fsh as the login shell. This was done to restrict access to certain machines and allow students to effectively have no limit while logged in. The new accounts will use an updates version of this as their login shell, which includes a limited shell to allow students to monitor their disk usage and the ability to use any shell as the subsiquent login shell.
