4.18 and 4.19 kernels are available in devel repo, and installation procedure checks if fs is mounted with LZ4 compression and will refuse to install in that case. But, it does not check if LZ4 compressed extends are already on the disk.
In that case, installing kernel 4.18 or higher will break current installation (fs would not be destroyed, but not longer mountable)

LZO - that has never been changed (image was always created with LZO compression enabled)

So in the future when you guys move the 4.18 or above from devel to main what can we do?
Is there a way to change the compression?

Also i kind of remember asking why we were using LZ4 some year ago here in the forum (or because i was having some random crashes)... are you sure LZO has always been the default compression? Because my current install/image is pretty old (as been updated/upgraded for years up to current) and i don't remember changing the compression type, and somehow its set to LZ4....

Thanks
