appimage portablility across machines (lemmy.today)

Hi everyone, I have been getting back into photography lately and switched to using linux full time about a year ago.

I ended up deciding to use digikam as my photo library management tool and then edit in darktable. both applications I decided to use the appimage for easier use and to have the necessary dependencies to get things like opencl to work, (I had a hard time getting it to work with the .deb)

now I also use multiple machines and recently learned that you can create .home and .config folders for each appimage to have all their settings etc save there, and it seems that this would make it pretty portable.

would it be a bad idea to for example keep the appimages and their folders in a synchronized folder like with nextcloud to use the same* appimage across machines. I never have the same machine on at a time but it would be nice to have all the settings sync'd but im not sure it would then break something since two machines use nvidia gpus and the other uses an amd gpu

You wouldn't be able to reliably map the XDG config folders you're mentioning to a network share. You won't have any issues running the appimage from a network share though. Just take a finalized config and drop it in the same location as the appimage and copy it where you need it.

An alternative would be to have a network mount with a portable user config for your entire profile, but it'll be quite a bit of work and require some pam finagling.

ok so a network share wouldnt be a good idea but what about a sync tool like nextcloud where it will just make a new copy to any machine I sync the nextcloud folder too?

I wasn't aware Nextcloud had a feature like that, but if it can sync the single flat file to where it needs to be, go for it.

If you want to get more detailed about it, have a look here: https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/6/html/deployment_guide/sssd-ldap-autofs

So I tried running dsrktable from the syncd nextcloud folder, first on one machine then when I got home on my desktop and everything seemed to run fine. After a while I was importing more and more photos then nextcloud started to complain about the database being too large to sync so that is a bit of a issue. Really the only thing I wanted was to sync settings so I just copied it out of my nextcloud folder and put it in my documents so I won't sync anymore

That's...odd. Sure sounds like it wasn't storing the DB locally, which shouldn't the default at all.
