I wanted to ask if ubuntu-core by design is behaving more like a ramdisk based OS? According to this page:
The OS and application files are kept completely separate, as a set of distinct read-only images.
which I understand as there are far less write operations done to the physical storage - I'm thinking of an SD card in my particular case. Would result in a more power-failure resistant storage (of course not talking about damaging the SD card itself)?
For reference - I have not too good experience with rPi's and their SD card based FS (don't get me wrong, I like them but they don't fit all of my use cases) which ended up corrupted... No matter what class of SD card I'd use I always ended up with a damaged system after some time. From what I've read this is normal since by default there's a lot of writes done by Raspbian and if power failure happens during write it makes the whole system not bootable.
As in some events I don't always have the luxury of shutting the system down with a proper
shutdown thus I'm looking for an OS more resistant to this and ubuntu-core seems to promise this. Am I understanding this right?
