It is tested to work, but maybe the desired semantics need to be better specified. The patch makes -l and additional and independent condition that can be app= lied to the list generated by -t <type,...>. An alternative concept would be to allow for multiple -t options and to make each operate on the list of file systems selected at this point. The traditional behavior of e.g. "df -t notmpfs,noufs" would be to list all file systems, since a set union is performed for each parameters of -t (i.e. all file systems that are not tmpfs are added to the list, then all that are not ufs ...). With multiple -t options allowed, -l could just be equivalent to the list of all local file systems specified with -l. In that case, a later "noufs" cou= ld delete file systems from the list (and a -l would delete all currently in t= he list that are not local). But that would be a much more complex change and not that useful since it is not expected to work by currently existing scripts. --=20 You are receiving this mail because: You are the assignee for the bug.=
