Prior to Red Hat Enterprise Linux 5.5, the --log option in anaconda was
not aware of whether %pre and %post scripts in kickstart files were
running in a chroot environment or not. Therefore, kickstart files had to
provide absolute paths to log files. Improvements to anaconda in Red Hat
Enterprise Linux 5.5 made the --log option aware of chroot environments.
Consequently, if unmodified kickstart files from Red Hat Enterprise Linux
5.4 were used to install Red Hat Enterprise Linux 5.5, anaconda sometimes
crashed and reported that the directory did not exist. The --log option
is now further modified to accept either absolute or relative paths. The
presence of absolute paths does not prevent the use of kickstart files
created for earlier versions of Red Hat Enterprise Linux 5.
