ok can someone explain why just doing
ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime
is bad?
here's what redhat recommends:
Update /etc/localtime by hand after installing the latest tzdata
package. This can be done with a simple copy command:
* cp /usr/share/zoneinfo/$CURRENT_TIMEZONE /etc/localtime
* where $CURRENT_TIMEZONE is your local timezone (e.g., America/NewYork).
why copy? why not symlink? (or even hardlink?)
