 The code in audacity:src/DirManager.cpp looks a little like this:

    wxLongLong freeSpace = 0;
    if (wxGetDiskSpace(globaltemp, NULL, &freeSpace)) {
       if (freeSpace < wxLongLong(wxLL(100 * 1048576))) {
          ShowWarningDialog(NULL, wxT("DiskSpaceWarning"),
                            _("There is very little free disk space left on
 this volume.\nPlease select another temporary directory in

 This shows 100MB is required.  /tmp has roughly 50MB on our builds, set by
 /etc/fstab which is probably set by olpc-os-
 builder:modules/base/kspost.10.core.inc .  Temporarily increasing the
 allocation for /tmp removes the warning:

 mount -o remount,size=128M /tmp

 This can be considered a workaround.

 The warning is useful, so I don't think it should be suppressed.

 I do not recommend moving the working area to eMMC or microSD without
 complete testing of recording throughput.
