file.
Modify the logic in the previous but one commit - /sbin/nologin should
be considered a valid user shell, since otherwise, with the addition
of the checks for a valid user shell, useradd with a shell of
/sbin/nologin will fail.
Modify some of the code here to conform to the standards in the rest
of this file.
- Fix error messages, some are completely incorrect
- Asystem prints the error message so don't bother saving errno
- Don't continue if a lock can't be obtained on /etc/group
- Just pass struct passwd * to removehomedir, not its members
Some copyright maintenance:
- Add Liam Foy.
- Move Todd's copyright higher up.
XXX: We should remove clause 3 and merge the two copyright groups.
- Correct lenght for the username
- First character in the login name cannot be '-' (OpenBSD)
- Remove some #ifdef EXTENSIONS. find_group_info is always needed
- When printing change, if it's -1, place a correct string.
*tp > LONG_MAX is never true, so replace that check with a test
for strtol() setting errno == ERANGE (oddly, some ports' build
swallowed this without warning).
There's no guarantee that a time_t stores the same number of bits
as a long, so check for an overflow there as well, and pass any
error up.
Discussed with christos, martin and mrg.
- Add new -C option to 'usermod'. This allows a quick way to temporary
lock a users account. This is similar to how FreeBSD do it using
'adduser'. This function can be very handy to administrators!
- Import a function to check if the inputted class actually exists. It
contains my modifications to test whether /etc/login.conf exists
in the first place. -OpenBSD

While I am there:
- KNF (long wrapped lines, and spaces after void casts).
- Factor out some common code.
- Fix error messages.
1. Consistently capitalize them.
2. Fix err->errx and warn->warnx inappropriate uses.
3. Use regerror where appropriate.
4. Don't call warn()/err() to report errors after you trashed errno
by calling other syscalls. Save and restore the errno instead,
or in the warn() case, call warn() first.
- Fix size_t - int, uid_t - int confusion.
- Pass lint
- system(), rmdir() sets errno, use it
- Use warnx() if strchr failed, not warn()
- Constify some arguments
- Fix cases when errx()/warnx() should be used instead of err()/warn()
due to errno not being set.
Group code:
------------
- List members in a neat fashion, separated by commas
- groupmod(): Use find_group_info - consistency
