The whole kpathsea should be replaced by a compressed database of
files accessed by flat file names with a separate index for each of
the various search categories.


would then use the "ist" index into the given database file name for
lookink up index style files.

Something like that.

No ls-R.  That would make TeXlive fast, compact, multi-user capable
also when writing, and would render the compression discussion moot.
