I have look, but start or mount script are call too late, as I said in my first
message, I'd like to execute a script before mounting the rootfs for the VE, so
maybe it can be done by adding a $VEID.premount and be place just after the
vps_is_run test.

I'm not very familiar with this syntaxes but I think it can be done similarly :

snprintf(buf, sizeof(buf), VPS_CONF_DIR "%d.%s", veid,
         START_PREFIX);
if (stat_file(buf)) {
         if (vps_exec_script(h, veid, res->fs.root, NULL, NULL,
                 buf, NULL, 0))
         {
                 ret = VZ_ACTIONSCRIPT_ERROR;
                 goto err;
         }
}

I'm investigate more into the code, and refresh some C knowledge to understand this

ok, I never use git before, but I will
