From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

When you start talking about offline then you're going to run into consistency issues and conflicts. How will a system automatically determine which edit to a file is correct if they were both edited offline?
I'm fairly certain Ceph is also going to be online only. You won't be accessing your CephFS filesystems when you take your laptop offline since they're part of the object store.
Something like Syncthing (as @Max_P@lemmy.max-p.me suggested) or some other 'Dropbox-like' self-hosted solution might be the way to go for what you're doing. Even then you'll probably only want to replicate a subset of your home directory - for example I'd skip temp and cache files that a lot of programs create.
If you want to play with Ceph just for the sake of doing so then don't let me stop you though :)
