It may be complicated, but the locate bundled with findutils is not
appropriate for some systems. It shows the existence of files that a
user should not ordinarily be able to see. Mlocate, being derived from
slocate (secure locate), doesn't have this issue. Also I remember
findutils locate being noticably slower at searching the database than
slocate, but I may be going back to when findutils depended on perl.
I'm going to hate myself for saying this, :) but I'd like to modify
findutils, & also take on the mlocate spell if Kevin doesn't want to
persist with it. I'm wondering which is the best way to modify
1: findutils optionally depends on mlocate.
2: findutils optionally doesn't install locate.
I prefer #2 as locate isn't strictly needed, there may be no use for it
at all on a very small system. Also it 'feels purer', it doesn't
introduce a dependency only to satisfy expectations. Any comments?
The modification to not install locate is actually quite simple, & goes
in PRE_BUILD rather than INSTALL. All that's needed is a sed command to
remove "locate" from the SUBDIRS setting in the makefile.
