# Kernel tags:
# Tags files are built in the top-level directory for each architecture,
# with a makefile listing the architecture-dependent files, etc.  The list
# of common files is in ./Make.tags.inc.  Links to the correct tags file
# are placed in each source directory.  We need to have links to tags files
# from the generic directories that are relative to the machine type, even
# via remote mounts; therefore we use symlinks to $SYSTAGS, which points at
# ${SYSDIR}/${MACHINE}/tags.

SYSTAGS=/var/db/sys_tags
SYSDIR=/sys

# Directories in which to place tags links (other than machine-dependent)
