You must also delete the old slocate.db as you do not know for certain whether it does or does not affect the initial run of mlocate's updatedb > PRUNEPATHS="/tmp /var/tmp /root/.ccache /media/stuff/backup/gentoo32" > > the last folder is my 32bit chroot. > and i got arround 225 gb of data. i tried running a few qurries .. seems to > have indexed everything > > also after this i tried deleting /var/lib/mlocate/mlocate.db and then > running updatedb and it hardly took a second. > > time updatedb > > real 0m0.367s > user 0m0.193s > sys 0m0.167s > > weird indeed.
