This option appears to allow you to file the TL, but you may find it's not possible to download only parts of a TL/SP any more.
FilterSysFile
Specifies the name of the file containing the list of installed software to
filter against (generated with lslpp -Lc) or the name of a system to filter
against. If filtering against the local system, "localhost" should be used. If
no filtering against installed software is desired, /dev/null should be used.
In a NIM environment, a NIM client can be specified.
