newfs with `-m 1'
This is needed even with `-o space' as the kernel decides to be "helpful"
and not really do space optimization. Looking at src/sys/ufs/ffs/ffs_alloc.c
we see why: if (fs->fs_minfree <= 5 ||
fs->fs_cstotal.cs_nffree >
(off_t)fs->fs_dsize * fs->fs_minfree / (2 * 100))
break;
log(LOG_NOTICE, "%s: optimization changed from SPACE to TIME\n"
I have picked `1' vs. `0' just incase some code somewhere has the assumption

Helped with understanding why -m 1 made a different: imp
