RE: [Voyage-linux] help with sync scripts
Hi Rob, all data will by synced to CF with 'voyage-sync sync', but be care ONLY in a special directory '/.sync/...'. Syncing directly to '/var/log' as example in a running system is not possible. If you call 'voyage-sync sync' and simulate a power outage, all your saved data is available under this directory until 'voyage-sync stop' ist called. With this option all data from ramdisk is synced to '/.sync/...', any process accessing this fs is killed, the directory gets unmounted from RAM and then a sync from '/.sync/var/log' to '/var' on CF is executed. So only if voyage-sync with option 'stop' is called your data gets sync to the correct place on the CF but also any process accesing this fs will get killed, so this should only be an option on shutdown. I belive it should possible to extend voyage-sync to detect a reboot with data remaining in '/.sync/...' from a previously sync and copy this data over to the correct place before syncing and mounting to ramdisk. If there is interest I can help. Also I will send Punky a diff to extend voyage-sync (from experimental) with additional output to show this behaviour. regards, Hermann -Original Message- From: voyage-linux-bounces+h.hofer=ahsnet...@list.voyage.hk [mailto:voyage-linux-bounces+h.hofer=ahsnet...@list.voyage.hk] On Behalf Of Robert Rawlins - Think Blue Sent: Tuesday, November 17, 2009 11:50 AM To: voyage-li...@voyage.hk Subject: RE: [Voyage-linux] help with sync scripts Hey Rodney, Thanks for the reply, I appreciate your help on this.

RE: [Voyage-linux] help with sync scripts
Hey Hermann, Thanks for taking the time to explain that to me, that makes perfect sense! I understand what you're saying! That proposed solution you talk of certainly sounds good, so the ./sync folder is effectively copied over on boot rather than shutdown, that way of the power is lost then the synced copy of the folder will be restored when the system next comes back to life rather than needing a proper shutdown/reboot. I'm more than happy to test some sync script ideas if you have any on how that might work, sounds like a very nice option. Unless of course Punky has a good reason for not implementing it into the build, which he may have.

Re: [Voyage-linux] Building Voyage: resulting ISO does not boot
Hi Roel, I have build the live ISO under VMWare with Voyage SDK. And the generated ISO is bootable. What is the live-helper version on ubuntu? Regards, Punky Roel Huybrechts wrote: Dear list, I'm trying to build the Voyage Linux distribution using the Debian Live configuration provided in SVN [0]. After issuing the command 'build.sh iso' as root the building starts and finishes successfully - from my point of view that is. However, the resulting 'voyage-current.iso' image fails to boot (in Qemu) with the error "Could not find kernel image: live". Is this an issue in the build configuration or lies the problem elsewhere in my setup (I'm using an Ubuntu 9.10 system)? If you need more information, please feel free to ask.

Re: [Voyage-linux] Building Voyage: resulting ISO does not boot
Hi, My Ubuntu uses live-helper version 1.0.5-1. I'm downloading the SDK now, as I understand that is the preferred way of building Voyage. I'll test with the SDK later this week.

Re: [Voyage-linux] Newbie question about initial Voyage install.
To clarify my last message, I tried using this serial port ir receiver: http://www.irblaster.info/receiver.html w/ my alix3c3 but it didn't work. Turns out it needs handshaking signals. USB ir receiver works well. I'm really pleased w/ the alix as a mpd device. It's been up for 403 days. I need to get around to figuring out how to integrate the picoLCD-4x20 I bought over a year ago to complete the project. ___ Voyage-linux mailing list Voyage-linux@list.voyage.hk http://list.voyage.hk/mailman/listinfo/voyage-linux
