It allows access to all files and subdirectories and is automatically recognized by all
Applications can still access files outside the virtual root normally (e.g.,
/dka100/foo/bar), but if
dka100 cannot be resolved, then

DECC$DISABLE_POSIX_ROOT will disable this support.
If you install GNV on your system, GNV establishes a root directory using the SYS$POSIX_ROOT concept. Generally GNV defines
the root directory, pointing to its main-level directory, generally on the system disk, at:
Within this root directory, GNV creates numerous standard UNIX directories:bin
Most of the GNV utilities are placed in
/bin. GNV configuration files are
/etc. GNV source files are in /src. Man page files are
