What I wonder about ...
True b-tree systems such as ReiserFS follow a b-tree allocation *AND
REALLOCATION* policy.
Yes file systems that use a model where the directories are just a
specially marked file (harks back to the old V6/V7 FS! WOW KISS) are by
their very nature going to have problems such as gaps for deleted files
and quite probably linear searches.
Perhaps that's why Postfix and others use a slightly hierarchical
"indexing" scheme. Many email systems are high throughput and this
seems to be one tactic Postfix uses.
If the directories are part of a b-tree then a whole host of problems
about allocation and searching go away.
Hmm. Other problems arise, but that's another matter.
