but $TMPDIR may not be defined in the environment, so we need --tmpdir / 
-p to specify the directory
-p is support on most of versions.

mnt_pnt=`mktemp -d $TMP/mnt_pnt.XXXXXX` doesn't work well

lina@lina-desktop:~$  export TMP=/home/lina/tmp/
lina@lina-desktop:~$ mktemp -d $TMP/mnt_pnt.XXXXXX
/home/lina/tmp//mnt_pnt.i12144
lina@lina-desktop:~$ mktemp -d -p $TMP mnt_pnt.XXXXXX
/home/lina/tmp/mnt_pnt.Q12146

if $TMP include / in end, then there will be 2 // for the temp file
