ok - with that qualification i understand.

still, especially for someone like me who frequently deals with source
code, 'locate' is indispensible.

and the fact is: updatedb discards a considerable portion of the cache
completely unnecessarily: on a reasonably complex box no way do all the
inodes and dentries fit into all of RAM, so we just trash everything.
Maybe the kernel could be extended with a method of opening files in a
'drop from the dcache after use' way. (beagled and backup tools could
make use of that facility too.) (Or some other sort of
file-cache-invalidation syscall that already exist, which would _also_
result in the immediate zapping of the dentry+inode from the dcache.)
