[13:05] didrocks, not much since that forces you to be online [13:06] didrocks, well, we could add it with an online check i guess ... but the whole thing is designed so that you can also use it witouth being online at all [13:10] ogra_: well, when you install the snap, you are online already, correct? :) [13:10] true indeed [13:11] and it we can try to make it ran only at that time? [13:11] I'm happy to have a shot at it [13:11] (not today) [13:11] but just wanted to know if you were +1 first on it [13:11] sure, the script that gets executed is actually shipped in the core snap [13:11] and is only executed the first time you run "sudo classic" [13:11] seems like a snap installed app can't read from the keyboard?

[21:14] mwhudson: snap-run -> snap-exec: we can run a patched dynamic linker at that stage [21:15] mwhudson: exec: we can use a patched glibc that uses an alternate linker if the target is in the core snap [21:15] mwhudson: I think we should not restrict what classic confinement snaps can run [21:15] mwhudson: it would limit their usefunless heavily IMHO [21:15] yeah it's a pretty blunt instrument [21:16] zyga: hey, yes [21:16] mwhudson: do you see any alternative ideas?
