To have your ext2 and ext3 filesystems fsck'ed correctly without explicitly
invoking the fsck_ext2fs utility installed by this port you will need to
create links or copy the fsck utilities installed by this port in/to /sbin, e.g.

ln -f "${PKG_PREFIX}/sbin/fsck_ext2fs" /sbin/ 2>/dev/null \\
  || install -m755 "${PKG_PREFIX}/sbin/fsck_ext2fs" /sbin/
ln -f "${PKG_PREFIX}/sbin/e2fsck" /sbin/e2fsck 2>/dev/null \\
  || install -m755 "${PKG_PREFIX}/sbin/e2fsck" /sbin/e2fsck

IMPORTANT: you also need to repeat the steps above after a port upgrade!

_EOF

	if yesno "Shall I create the links now?" yes ; then
		echo "Installing /sbin/fsck_ext2fs and /sbin/e2fsck."
		ln -f "${PKG_PREFIX}/sbin/fsck_ext2fs" /sbin/ 2>/dev/null \
		  || install -m755 "${PKG_PREFIX}/sbin/fsck_ext2fs" /sbin/
		ln -f "${PKG_PREFIX}/sbin/e2fsck" /sbin/e2fsck 2>/dev/null \
		  || install -m755 "${PKG_PREFIX}/sbin/e2fsck" /sbin/e2fsck
	fi
fi

if [ "x$2" = xDEINSTALL ] ; then
	cat <<_EOF

If you are deinstalling the e2fsprogs port for good, rather than upgrading it,
remember to remove the files you may have installed into /sbin, example:

rm -f /sbin/fsck_ext2fs /sbin/e2fsck

_EOF

	if yesno "Shall I remove the links now?" yes ; then
		echo "Removing /sbin/fsck_ext2fs and /sbin/e2fsck."
		rm -f /sbin/fsck_ext2fs /sbin/e2fsck
	fi
