The logic is not to exclude R/O file systems, but R/O file system
*types*. E.g., an UFS root is scanned, whether mounted R/O or R/W
(since it is a writable file system type) but a CD9660 root would
I was not sure about inclusion of this condition, but since CD and
DVD drives have slow seek times (and removable media), this seemed
reasonable to me.

The most common is cd9660, but the VFCF_READONLY flag is also set
for UDF and ReiserFS (and possibly some file systems available as

not match your expectations. I do not have all file system types
available for testing (e.g. none of the fuse-fs sub-types and no
You can always override the file system types to inspect in the
