+the same arguments can be set as volume flags, in addition to `d2d`, `d2ds`, `d2t`, `d2ts` for disabling:
 * `-v ~/music::r:c,e2dsa,e2tsr` does a full reindex of everything on startup
 * `-v ~/music::r:c,d2d` disables **all** indexing, even if any `-e2*` are on
 * `-v ~/music::r:c,d2t` disables all `-e2t*` (tags), does not affect `-e2d*`
+* `-v ~/music::r:c,d2ds` disables on-boot scans; only index new uploads
+* `-v ~/music::r:c,d2ts` same except only affecting tags
 
 note:
 * the parser can finally handle `c,e2dsa,e2tsr` so you no longer have to `c,e2dsa:c,e2tsr`
