think it will. As I said I'd try it from willow but I can
imagine, that eg. expiring tiles won't work this easy when osm2pgsql
does not run on the same machine as mod_tile.
Expiring tiles is a different matter, but osm2pgsql doesn't expire the
tiles directly so shouldn't effect where it has to run. Instead it spits
out a textual list of tiles that should be considered expired, that then
needs to be handled separately. The actual expiry script will most
likely need to be run on the same machine as the (meta)tiles stored
though, as it does require to touch and stat quite a lot of files.
Especially with the 200 different language styles. But if the meta tile
directory is writable from the login servers, we can experiment with
what setup works best first before moving it over to ptolemy.
Note also that osm.org
doesn't use osm2pgsql for expiring tiles, they
have a custom script that doesn't look at relations. The reason for it
is that some edits to large relations can expire a lot of tiles IIRC.
I can't recall where the script is but it's some ruby script in OSM SVN.
