This is a good point, but it may break upgrade as right now there is no user interaction, whereas apkg -u always has user interaction and this IMHO would be a major drawback. Why would this be a major drawback? Because of the necessity of user interaction. It is my understanding that the upgrade script downloads the files to your mountpoint/local storage.

There should be a way to preserve user settings without touching the contents of system files. Maybe we should just save the differrences to the original files and apply them to the freshly loaded files at system start. Maybe you can enhance upgrade to also upgrade the running system with apkg -u, as second step, you'll get all the benefits of the upgrade logic of apkg. Yes this requires user action, but without you either miss new config settings or you lose your changes to the config files. Possibly, if apkg really detects all incongruities. The last step would be to svae the changes to configdb. Of course It will be easy to implement this although I do not like it. I will certainly look into a way to preserve user changes, but that will be major work and take some time. cheers ET smime.p7s Description: S/MIME Cryptographic Signature -- ___ leaf-devel mailing list leaf-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-devel

This is a good point, but it may break upgrade as right now there is no user interaction, whereas apkg -u always has user interaction and this IMHO would be a major drawback. I don't know if there is an option to apkg which makes it silent and just use the new file, but that could probably be added. Nevertheless, if apkg could overwrie the package then we still would have to save configdb, but that is not so bad. Unfortunately, there could be a loss of valuable information in configdb. Maybe it would be enough to inform the user of the differences in important config files.

You are right, if you have saved previously changes in fstab to configdb.lrp and just *replace* etc.lrp, providing an updated fstab, your saved fstab will overwrite the new one - and consequently you'll be missing the changes. This does not happen, if one adds a new etc.lrp with "apkg -u", where changes between confg files are noticed to the user, who can then decide to Keep the old file, to Replace it with the new version, to Show differences or to Edit a merge file. Can your upgrade script handle this better (does it run apkg -u for Packages?), than the sole replacement of the Package file?? This would be a welcome improvement. > Had I upgraded the router previously to 5.x this would probably have > occurred earlier, it is a 4.x to 5.x issue.

I added stuff to /etc/fstab locally, actually completely legal and saved the changes to configdb, thus the fstab was overwritten and lacked the entries for the newly created mount points in 5.x. Had I upgraded the router previously to 5.x this would probably have occurred earlier, it is a 4.x to 5.x issue. I suggest to document this in some gotcha section of an upgrade guide. cheers ET -- Full-scale, agent-less Infrastructure Monitoring from a single dashboard Integrate with 40+ ManageEngine ITSM Solutions for complete visibility Physical-Virtual-Cloud Infrastructure monitoring from one console Real user monitoring with APM Insights and performance trend reports Learn More http://pubads.g.doubleclick.net/gampad/clk?id=247754911&iu=/4140 ___ leaf-devel mailing list leaf-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-devel
[leaf-devel] pty allocation failure
Hi KP you apparently had the same failure about 2 years ago. I could not find the solution in the archives though. debug1: Allocating pty. openpty: No space left on device session_pty_req: session 0 alloc failed Thanks ET smime.p7s Description: S/MIME Cryptographic Signature -- Full-scale, agent-less Infrastructure Monitoring from a single dashboard Integrate with 40+ ManageEngine ITSM Solutions for complete visibility Physical-Virtual-Cloud Infrastructure monitoring from one console Real user monitoring with APM Insights and performance trend reports Learn More http://pubads.g.doubleclick.net/gampad/clk?id=247754911&iu=/4140 ___ leaf-devel mailing list leaf-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-devel
