Unlike vacfs(4), vacsrv handles multiple 9P2000 and venti requests concurrently, and keeps an internal cache of venti blocks and directory lookups. It is fast enough to serve as a root file system. Vacsrv is currently read-only.

Options:

-d

Print debug info.

-n

Before mounting, create a new empty namespace. Only useful in combination with -m.

-p

Print each score and its type requested from venti to the standard output. This is used by vacinits vacwalksrv to return a list of scores required for reading a list of files.

-s

Print 9P2000 (styx) traces.

-t

Print venti traces.

-V

Do not verify data returned by the venti server. By default, data is verified to match the requested score.

-a addr

Use addr as the venti server, instead of the default ndb name $venti.

-m mtpt

Mount on mtpt. If not specified, vacsrv serves 9P2000 on its standard input.
