OS/2 file system is based on drives[A-Z]. '/' means a root of a current drive. There are maximum 26 kinds of '/'. For examples, consider that xxx is installed into f:/usr/bin. If executing xxx on drive e:, '/' of xxx is e:/ not f:/. In this case, xxx fails to find its root. $UNIXROOT is used to overcome this problem. On OS/2, $UNIXROOT is used to specify a drive of '/'. And all programs following FHS are installed on a drive specified by $UNIXROOT. In the above, if UNIXROOT is set to 'f:'. Then '/' is translated to 'f:/' as xxx expects. And see <http://trac.netlabs.org/libc/wiki/UnixPenthouseApartement>.
