# MCONFIG -- Configuration stuff for util-linux

# For a user-mode install, make (at least) three changes:
#  - remove the `-o root' part in INSTALLSUID
#  - set USE_TTY_GROUP=no
#  - define DESTDIR

DESTDIR=../output

## Configuration outside of this file you might want to do for mount:
## If make_include has HAVE_BLKID=yes, turn that into HAVE_BLKID=no
## if you do not want to use the blkid library.
## In mount/realpath.c turn #define resolve_symlinks into
## #undef resolve_symlinks if you use devfs and hate long names.

# Select for ARCH one of intel, alpha, sparc, arm, m68k, mips
# Select for CPU i386 if the binaries must be able to run on an intel 386
# (by default i486 code is generated, see below)

# it sets MAY_ENABLE_NLS in defines.h. If you don't want NLS, set
# DISABLE_NLS to "yes".
