DaemonNews: "During installation it is important to size filesystems so that we won't be forced to resize them later. However, it often appears with time that one of the partitions is too small. Until today it was impossible to
expand the size of a filesystem. FreeBSD 4.4-RELEASE comes with a new utility: growfs(8). This program permits us to enlarge, in certains conditions, the size of an existing ufs filesystem."
