enabling the sudoedit_follow option in sudoers or on a per-command
basis with the FOLLOW and NOFOLLOW tags.
Locking of the time stamp file has changed in sudo 1.8.15.
Previously, the user's entire time stamp file was locked while
retrieving and updating a time stamp record. Now, only a single
record, specific to the tty or parent process ID, is locked.
This lock is held while the user enters their password. If
sudo is suspended at the password prompt (or run in the
background), the lock is dropped until sudo is resumed, at which
point it will be reacquired. This allows sudo to be used in a
pipeline even when a password is required--only one instance
of sudo will prompt for a password.
o Upgrading from a version prior to 1.8.14:
On HP-UX, sudo will no longer check for "plugin.sl" if "plugin.so"

authentication users. On systems that support it, monotonic
time is stored instead of wall clock time. As a result, it is
important that the time stamp files not persist when the system
reboots. For this reason, ther default location for the time
reboots. For this reason, the default location for the time
stamp files has changed back to a directory located in /var/run.
Systems that do not have /var/run (e.g. AIX) or that do not clear
it on boot (e.g. HP-UX) will need to clear the time stamp
directory via a startup script. Such a script is installed by
directory via a start up script. Such a script is installed by
default on AIX and HP-UX systems.
Because there is now a single time stamp file per user, the -K
option will remove all of the user's time stamps, not just the
time stamp for the current terminal.
Lecture status is now stored separatedly from the time stamps
Lecture status is now stored separately from the time stamps
in a separate directory: /var/db/sudo/lectured, /var/lib/sudo/lectured
or /var/adm/sudo/lectured depending on what is present on the
system.
