This can be done in the menu presented at initial boot.

It will not work properly for other volumes despite any additional check-boxes you might see. Installer and boot-time support works but is still a bit rough around the edges. Performance will be relatively high on multi-core machines. **ISA driver removal** - A number of ISA hardware drivers have been removed. One of these drivers, ie(4), was in our GENERIC config. Another driver, aha(4), was in both our GENERIC and our X86_64_GENERIC kernel configuration files. If you are using a kernel config based on a previous release's GENERIC config file, you may need to remove these drivers in order to successfully compile the kernel. **PAM Changes** - The pam_krb5 and pam_ksu modules have been removed as part of a PAM update. If you were using these modules, the security/pam-krb5 package in pkgsrc is a suitable replacement. +**crypt(3) / master.passwd changes** - Improved crypt(3) routines have been implemented as +part of this release. New installations will use sha512 format passwords, with improved +hashing available for the previous sha256 default.

Specifically, building world with more than 4 processes (-j 5) may cause issues on i386, and some users have seen issues with NFS.
