Ooh! Good call about subdir .-dirs being counted anyway...

"more suggestions" ? Only of the 'clutching at straws' variety,

like
"do you use chattr to set files as {able to be undeled later}?
but that is the 'u' feature>

or like
"have you used exotic mke2fs settings to retain 95 percent
of the filesystem space reserved for root userid admin purposes,
instead of the default 5 percent of total capacity?"
<>

or like
"if you mount some other computer's disk share on this box,
and copy your various major directories over there,
does this phantom disk usage get copied over too?
