If that's true (which I highly doubt, more probably you don't know how to read them), then it's a bug and should be reported and fixed. I read log files with less. The bug is that systemd uses some sort of binary files, and they aren't going to fix it. They even won't fix their misunderstanding of what disabled means.

Doing any of that stuff requires the use of software capable of reading text files. It isn't like you can just interpret the magnetic fields on your disk with your eyes. Yes, and it doesn't seem very likely that it'll become impossible to read text files in the next 20 years. Sure, there are a lot more utilities that can read text files than journal files, but you just need to arrange to have them handy. They'll be ubiquitous before long since every distro around will end up needing them. Hopefully not, systemd is a bad thing for many reasons. Can you do all that with the binary files created by systemd? I can't even read them on a working system. You just type journalctl to read the live system logs. For offline use you just type journalctl --file=filename. Or you can just run strings on the file I imagine if you're desperate. If it doesn't work on a working system then your system isn't working. See, ppl already claim that when something that comes from systemd isn't working, then the system isn't working. Unfortunately, they overlook that when things systemd don't work by design, it's bad design or a problem of systemd rather than the system not working. -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us.

Marc Joliet mar...@gmx.de writes: Can you do all that with the binary files created by systemd? I can't even read them on a working system. What Canek and Rich already said is good, but I'll just add this: it's not like you can't run a classic syslog implementation alongside the systemd journal. On my systems, by *default*, syslog-ng kept working as usual, getting the logs from the systemd journal. If you want to go further, you can even configure the journal to not store logs permanently, so that you *only* end up with plain-text logs on your system (Duncan on gentoo-amd64 went this way). So no, the format that the systemd journal uses is most decidedly *not* a reason against using systemd. It is only one of the many reasons. I don't find it advantageous to have to waste additional resources to be able to read the log files. Personally, I'm probably going to uninstall syslog-ng, because journalctl is *such* a nice way to read logs, so why run something whose output I'll never read again? If you like it, nobody prevents you from using it. It's good to have many options. Just don't force others to use it as well. -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us. Finally, this fear has become reasonable.

You do get the increased space but you don't get much in the way of flexibility. And it get COMPLICATED really quickly. It certainly can, but for a simple two drive home system it shouldn't get out of hand. However, it does avoid the one disk errors kills two disks' data problem. Yea, right now, I'm only using two drives. One for the OS and one for /home. I have a third drive but it isn't in use. I'm thinking about moving everything but the videos to that drive, 750GB, and leave just the videos on the large 3TB drive. It'll free up a *little* space too. To get around the situation of one drive almost full and the other having lots of space, folks often use symlinked directories, which you forget about and no-one else can figure out what you did... I wasn't suggesting symlinks, just LVs mounted at appropriate points. It rather depends on the spread of Dale's data. If he just needs extra space for his videos, he could get a new drive and mount it at ~/videos. The bulk of the space is used by the videos. It's everything from TV shows to movies to youtube howtos. I'm using roughly 1.8TB on the drive and the videos take up roughly 1.7TB of that space. My camera pics only use 21GBs of space. Rest is basically a rounding error. :/ It all smacks of the old saw: For any non-trivial problem, there is always at least one solution that is simple, elegant, and wrong. :-) I consider what I suggested somewhat simple but far from elegant. Often though, it's a lot less work in the long run to go for the initially more complex solution. If Dale is worried about the likelihood of disk failure, he really should be using RAID - either MDRAID under LVM or one of the next-gen filesystems. I really do need to set up RAID at least for some stuff that I may not be able to get back. Some videos I have are no longer available.

Oh, and it is all on RAID too, which reduces the risk of needing to actually restore it (RAID is primarily about downtime, not backup). Encryption keys are burned to multiple CDs and stored in multiple safe places. Photos and other valuable media: Also gets the duplicity S3 treatment, but after every few GB I do a one-time upload to Glacier and then remove it from my daily backups. This stuff is write-once, so backing it up daily is overkill. When S3 was more expensive I would burn two copies to DVD and store offsite, but that became a PITA and Amazon is a lot cheaper now. If I ever need to restore it it is unlikely I'd need it all at once, so I can do so slowly and not get killed by fees. MythTV recordings, random video from internet, etc: btrfs raid plus a second daily rsync to ext4 (still local). The rsync is only because I'm still in playing-around mode with btrfs. Once I trust it fully I'll drop it and just rely on the RAID. I'd be annoyed if I lost all this stuff, but only for a week or two.

If all the libs and programs were going as 64-bit code, to my 32-bit-only machine, Gentoo should be badly broken by now, to the point of being unbootable. The problem appears to be isolated to seamonkey. I'll first try adding -m32. If that doesn't work, I'll drop the pump option. I'll let you know how things turn out. -- Walter Dnes waltd...@waltdnes.org I don't run desktop environments; I run useful applications
Re: [gentoo-user] Hard drive storage questions
Greetings gents. I may have missed it, but i haven't seen this suggested yet: RAID+LVM. If you already have a 3TB drive, buy another (or two more) and build a RAID1 or 5 array on them. Then build your LVM on top of /dev/md0 (or whatever device your raid is). Another approach is ZFS with RAID-Z or similar. I don't know how/if ZFS splits data among the drives, but i assume it's wise enough to do so in a way similar to a RAID+LVM combo. If going RAID, make sure the rpm and cache are the same for performance's sake, and you can mix and match drives from different vendors (perhaps you should, to add to the redundancy). I don't know about btrfs, seems like it's still in a testing-phase so i'm not touching it yet. Just my 2¢ Cheers, Nuno
Re: [gentoo-user] Portage metadata cache backend: sqlite or not?
Oh wow, I completely forgot about this open thread. In my defense, I had to move out two (or was it three?) days after I started the thread, and didn't have internet again until over a month later.

It takes long time to generate metadata after sync and not really that advantageous. Also eix has it's own issues in this mode. Do I understand correctly: you recommend switching away from the sqlite backend? Also, can you please elaborate on the issues with eix?

Anyway, I also need to look into some sort of backup system. I used to do this with DVDs but with this much stuff, that just isn't a good idea, not to mention that DVDs have their own issues. I may take a peek into a RAID setup since really, that is about the best if not only way to do it. How often do you need to refresh your backups? And how much does a medium-size safety-deposit box cost in your area? Would the bank object to you going into your safety-deposit box once a month? Here's a plan... 1 computer with a main drive, and 2 backup drives. The backup drives are either removable internals, or standalone externals. In either case, they would have to fit inside the safety deposit box. Month # 1) make duplicate backups of your machine to both backup drives, and stick 1 into the bank safety-deposit box, and keep the other at home 2) - update your home backup - take it to the bank - swap it with the other drive - bring the other drive home and update that backup immediately 3) all succeeding months...

Basicly the makefiles are invoking the full compiler name for the files that are meant to run on the target but it invokes just gcc for the files that are meant to run on the host. This is in the context of cross-compiling, not distcc, so the file that's failing is meant to run locally (it's a custom build tool). If you where compiling locally (or in two machines with the same compiler) it would not matter cause the host and target compiler are the same, but when distcc comes in it builds those files with the host (system) compiler on the host. Changing the c++, cc, gcc, and g++ symlinks to a wrapper script that invokes the compiler by it's full name as show in the RaspberryPi wiki page *should* fix it. That sounds confusing cause I use host to mean distcc host at one point and host compiler on another. I will use server to refer to distcc host on this post. When you run a GNU standard configure script you can specify two compilers, the host and target compiler. When compiling locally they're both the same. But when cross-compiling the host is the system compiler and is used for compiling things that will be executed as part of the build process (most packages don't do this). On gentoo this is set from the CHOST variable on make.conf, but either it's not usually passed to configure scripts by portage or some scripts just ignore it and invoke the host compiler as cc, c++, g++, or gcc. When cross-compiling the target compiler is the one for the target architecture where the package will be deployed to. This is always invoked by the full name (on GNU compliant packages). Distcc just traps the compiler invocations on the client and perform the same invokations on the server. In your case the seamonkey is trying to compile something with the host compiler, distcc is trapping it and compiling it with the host compiler on the server. Since the host compiler in the server is not the same as the host compiler on the server things go bad. So you don't need -m32 unless you want to use the host compiler on the server. Since you want to use a cross-compiler on the server that was an ugly hack because you're actually using both compilers on the server. If the version of the cross-compiler gets out of sync with the host compiler things can go bad easily. So the proper fix in your scenario is to get rid of the -m32 and make the host compiler links a wapper script so that everything is compiled with the cross-compiler on the server. -- Fernando Rodriguez

On Mon, May 04, 2015 at 05:29:34AM -0400, Fernando Rodriguez wrote All you need to do is create scripts on the host with the exact same names and have them execute the compiler that you want with the options you want (I just have it execute the 64bit compiler with -m32). Then make sure that distccd (on host) finds them before the actual compiler by putting it in the PATH environment variable before anything else. Much to my surprise, adding -m32 to the client's CFLAGS (and therefore also CXXFLAGS) results in seamonkey building properly. I tried it out on the same video, and cpu load only climbs to 2.5 versus 2.75 with seamonkey-bin. The build took 1hr and 43 minutes on the Core 2 Duo host, versus 14 hours doing it on the Atom. Why is seamonkey the only program (so far for me) that needs -m32? Would it need -m64 if it was being cross-compiled on a 32-bit host system for 64-bit client?
