"rlocate is an implementation of the ``locate'' command that is always up-to-date. The database that the original locate uses is usually updated only once a day, so newer files cannot be located right away. The behavior of rlocate is the same as slocate, but it also maintains a diff database that gets updated whenever a new file is created. This is accomplished with rlocate kernel module and daemon. The rlocate kernel module can be compiled only with Linux 2.6 kernels." (from the page) I think if you have a 2.6 kernel (which is now default with Gentoo Linux), it is better to have rlocate than the normal slocate because (1) the database is always up-to-date and (2) the "fast" update only needs a few seconds compared to many minutes for slocate's updatedb. Reproducible: Always Steps to Reproduce: 1. emerge rlocate Actual Results: emerge: there are no ebuilds to satisfy "rlocate". Expected Results: >>> sys-apps/rlocate merged.

Shouldn't it be using one of the module eclasses? It should also block on slocate (in the final version), both install updatedb and locate symlinks. In addition, the module needs security support enabled in the kernel, which isn't a very common option. configure will (or should) bomb out without. I've also had problems building it against the kernel in /usr/src/linux instead of the running kernel (the configure option appears to do nothing), so it has to be rebuild after the reboot (breaking the new module-rebuild package) or with a number of hacks.
Sorry for the bugspam, but I can't get the ebuild to work. Snippets from the ebuild and a manual install: make[2]: Entering directory `/var/tmp/portage/rlocate-0.3.0/work/rlocate-0.3.0/rlocate-module' mv Makefile Makefile.automake cp ./Makefile.kernel ./Makefile make -C /lib/modules/2.6.11-gentoo-r9/build SUBDIRS=`cd . && pwd` modules \ KBUILD_VERBOSE=1 make[3]: Entering directory `/usr/src/linux-2.6.11-gentoo-r9' Makefile:531: /usr/src/linux-2.6.11-gentoo-r9/arch/x86/Makefile: No such file or directory make[3]: *** No rule to make target `/usr/src/linux-2.6.11-gentoo-r9/arch/x86/Makefile'. Stop. This is related to ${ARCH} which is used by the kernel. Adding in a "econf; unset ARCH; emake" src_compile function "works", but I highly doubt unsetting ARCH is the best way to do this. After that, it has a sandbox violation in the install part: /bin/install -c -m 644 rlocate.ko /var/tmp/portage/rlocate-0.3.0/image//lib/modules/2.6.11-gentoo-r9/misc/rlocate.ko /sbin/depmod -a ACCESS DENIED open_wr: /lib/modules/2.6.11-gentoo-r9/modules.dep.temp FATAL: Could not open /lib/modules/2.6.11-gentoo-r9/modules.dep.temp for writing: Permission denied After disabling the sandbox, it installs fine. But in order to actually keep the DB up to date, rlocated has to be run, probably from a initscript.

Works fine after adding "inherit toolchain-funcs".
thanks, now in portage ~x86

deleted the call to groupadd ... sync up and see if that fixes things
The problem is that no rlocate group exists. I solved this by just changing slocate to rlocate in /etc/group, but a solution should be put into the ebuild.
does rlocate need a rlocate group ? if so, we should probably unify the slocate/rlocate group handling into just a 'locate' group
Also, we should provide a proper init script for the rlocated daemon (whihc makes all this worthwhile...) Here is a simple one I whipped up (note the header stolen from the gkrellm script)
Created attachment 60223 [details] rlocated init script
(In reply to comment #10) > does rlocate need a rlocate group ? if so, we should probably unify the > slocate/rlocate group handling into just a 'locate' group Yes, it does. That is a fine idea. In case anything depends on slocate, we might eventually want a virtual dependency, too. Since rlocate is based on slocate's code and it meant to be compatible, this should be reasonable. One more thing: it may be good to check the kernel version. Since gentoo has all but abandoned 2.4, this may not be necessary, but the README of rlocate says "rlocate kernel module can be compiled only with 2.6.* kernels."
Sorry for the rapid-fire comments, but two more things I've noted: 1) a version bump is needed, to 0.3.1. This fixed a segfault in fast updatedb, which I personally experienced on every attempt. 2) /var/lib/rlocate needs to be created in the ebuild. I'll sit on my hands and let someone else play now...
ok, ive updated rlocate and slocate to use the 'locate' group
Created attachment 60735 [details] rlocate-0.3.0-r1.ebuild [EDIT 0.3.1-r1] You actually missed a couple chmods in the Makefiles, causing it to fail. This fixes that, and also installs the above initfile.
I'm sorry, make that 0.3.1-r1. forgot the version bump.
I've noted this error arising with the new "locate" group: rlocated: WARNING: Could not find the group: rlocate in the /etc/group file. rlocated: WARNING: This is a result of the group missing or a corrupted group file. so, I wonder if the rlocate group is hardcoded into the command somehow?
You should also modify RLOCATE_GRP=... in rlocate-daemon/Makefile.in
what a crappy build system added sed's to cvs, thanks
