2 :: What is LD_LIBRARY_PATH?

This is one system administrator's point of view why
LD_LIBRARY_PATH, as frequently used, is bad. This is written
from a SunOS 4.x/5.x (and to some extent Linux) point of
view, but this also applies to most other UNIXes.

LD_LIBRARY_PATH is an environment variable you set to give
the run-time shared library loader ( an extra set of
directories to look for when searching for shared libraries.
Multiple directories can be listed, separated with a colon
(:). This list is prepended to the existing list of
compiled-in loader paths for a given executable, and any
system default loader paths.

For security reasons, LD_LIBRARY_PATH is ignored at runtime
for executables that have their setuid or setgid bit set.
This severely limits the usefulness of LD_LIBRARY_PATH.

The cron daemon reads the /etc/cronlog.conf configuration
file provided by the user to log the information. If a
configuration file has not been created, then the cron
daemon creates a log of its activities in the
/var/adm/cron/log file. The cron daemon reads the
configuration file when it is activated and when it receives
the hangup signal.

If the cron daemon is not able to create or open the
user-specified logfile, then it creates a log of its
activities in the /var/adm/cron/log file.
