i'd suggest logging to a loghost, in clasic syslog.conf: *.* @loghost will send all logs to loghost machine, which has to be added to your hosts file. if you are using syslog-ng, it's slightly more complicated, but gives you more advantages! syslog-ng can send via TCP, so you can encrypt it

hm .. how about locks and other stuff ? there always some things which want to be written to somewhere in /var! the gentoo runscripts use /var/lib/init.d/ i reckon having a bit of space writable in /var and /tmp symlinked to /var ..could be usefull, keep one or two day's logs as well and log them

The whole idea of read-only is for two reasons: 1) To protect the HD in case of unexpected shutdowns (which could happen nightly in a typical museum situation) 2) To preserve the CF memory, which has a limited number of write cycles, in the case of a HD-less system If the computer needs to be

Flash memory, regardless of format, supports only a limited number of erase/write cycles before a particular sector can no longer be written. Memory specifications generally allow 10,000[1] to 1,000,000 write cycles. Typically the controller in a CompactFlash attempts to prevent premature

Come to think of it, are there any Linux distros for x86 architectures which don't use this multi-user/networked server paradigm and instead follow the embedded model more closely? This would be very interesting for exactly the situations I describe, where you would want the computer to behave

Either way could work, the ramdisk is a particularly good idea. Unless the installation is networked, there's not too much need for logfiles in the classic server or multiuser environment sort of sense. You could probably also just disable to logging daemon by removing it from the boot scripts

Can't use logrotate if the partition is mounted readonly. I can see the point if the idea wasn't to fill up disk space, but my whole idea is to not write to the disk at all. Symlink is also a good idea, though. best, d. Andy Farnell wrote: On Tue, 1 Jan 2008 21:57:18 +0100 [EMAIL

For installations, I've always tried to make the computer as bulletproof as possible. Usually, you have these guards or museum assistants who simply turn everything off (often with one mains switch!) every night, for example. You can make whatever documentation you want, but you can also
