Writing to System Logs

This isn't a RedHat specific question. The software in question might be used for any Linux distribution. Would it be advisable or inadvisable for my application, to be downloaded by many people I don't know, to write to the following logs in /var/log?

maillog or mail.log
messages
secure

Is there a reason not to do this, and if I do write to these logs, is ordinary file I/O good enough?

Thanks.

Brandon

CGRULESENGD(8)							 libcgroup Manual						    CGRULESENGD(8)

NAME
cgrulesengd - control group rules daemon SYNOPSIS
cgrulesengd [options] DESCRIPTION
cgrulesengd is a daemon, which distributes processes to control groups. When any process changes its effective UID or GID, cgrulesengd inspects the list of rules loaded from the cgrules.conf file and moves the process to the appropriate control group. The list of rules is read during the daemon startup is are cached in the daemon's memory. The daemon reloads the list of rules when it receives SIGUSR2 signal. The daemon reloads the list of templates when it receives SIGUSR1 signal. The daemon opens a standard unix socket to receive 'sticky' requests from cgexec. OPTIONS
-h|--help Display help. -f <path>|--logfile=<path> Write log messages to the given log file. When '-' is used as <path>, log messages are written to the standard output. If '-f' and '-s' are used together, the logs are sent to both destinations. -s[facility]|--syslog=[facility] Write log messages to syslog. The default facility is DAEMON. If '-f' and '-s' are used together, the logs are sent to both destina- tions. -n|--nodaemon Don't fork the daemon, stay in the foreground. -v|--verbose Display more log messages. This option can be used three times to enable more verbose log messages. -q|--quiet Display less log messages. -Q|--nolog Disable logging. -d|--debug Equivalent to '-nvvvf -', i.e. don't fork the daemon, display all log messages and write them to the standard output. -u <user>|--socket-user=<user> -g <group>|--socket-group=<group> Set the owner of cgrulesengd socket. Assumes that cgexec runs with proper suid permissions so it can write to the socket when cgexec --sticky is used. ENVIRONMENT VARIABLES
CGROUP_LOGLEVEL controls verbosity of the tool. Allowed values are DEBUG, INFO, WARNING or ERROR. FILES
/etc/cgrules.conf the default libcgroup configuration file SEE ALSO
