How does FOG operate at 0% capacity when capturing?
-
@salted_cashews No we really compress on the fly. In the Linux world this is done by using pipes. The output of partclone (reading the data from disk) is directly passed to the compression program (gzip, zstd, …) and only written to disk after that.
The delay in updating the “size on server” is because a service is running in the background to enumerate images sizes and write that to the database. So after an image is done it takes a couple of minutes till the “size service” comes along and calculates it.
I’ve tried to deploy during this process (before a real value is reported) and it breaks the image on the server as well as deploys a broken image.
Then exactly did you start deploying the image? Capture finished before deploy started? In which way did it break the image???
Any guides for a linux newbie related to safely cleaning up old kernel packages / boot partition?
Which Linux OS do you use?

@Sebastian-Roth For FOG, it’s Ubuntu 16.04.
It’s possible my memory is wrong, but I remember starting the deployment within a minute after the capture completed. I had waited for the task to complete and disappear from the web GUI’s “Active Tasks”. I could be thinking of the issue with the unclean Ubuntu file system I had made another topic about (still working on that situation btw) in which correlation might not be causation, that could’ve just been something I had noticed different and thought “well the size was 0 so maybe that’s why it broke, it didn’t finish compressing.” when in reality it could’ve just been the file system.

@salted_cashews Run
apt autoremoveas root and it should clean up for you. -
@Sebastian-Roth Oh that’s delightfully simple, thanks!
-
Ther’s also
apt-get -y autodelete -
@Wayne-Workman Is this one any different or is it basically a synonym command?
-
@salted_cashews It’s different.
-
@Wayne-Workman How so?
-
@salted_cashews Correction. This is what I use for updating Debian based systems:
apt-get update;apt-get -y dist-upgrade;apt-get -y autoclean;apt-get -y autoremove -
@Wayne-Workman Interesting, I found our problem was the initial setup of the Ubuntu server that hosts FOG was set to allow auto-updates. This will come in handy for future installs, thanks!
