16 As a workaround, I have my CVS checkout of the tree on a reiser3
17 partition with tail-packing enabled. This really helps, esp. as CVS has
18 4 files of overhead for per working directory. I'm not aware of any
19 other tail-packing read-write filesystems unfortunately. (I know that
20 read-only ones like squashfs etc. exist).
