- On one of our systems here, there are over 3000 entries in the passwd file.
- Every time a user wants to make a change to it (chfn, passwd, chsh), the
- file must be locked so the user has exclusive write access to it in order to
- make the change. With lots of people trying to do this all time, changing
- one's password can take an HOUR! First the user has to wait for a file
- lock, then the file has to be changed. The first part takes up most of the
- time. The situation is aggravated in the morning when the accouting
- programs take their tallies and turn off access for users who have exceeded
- their time quotas.
-
- Is there a way to split the passwd file into smaller chunks so it can be
- more managable? For example, all users with 0 < UID < 500 would be in one
- passwd files, all users with 501 < UID < 1000 would be in another, etc.
- This would reduce the lock and write times on the passwd file tremendously,
- I imagine.
