One of the most fundamental yet little-known features of FreeBSD is its ability to be used in read-only mode very easily. By installing the system on a UFS file system, you just need to modify the fstab file, change "rw" to "ro," and reboot. On the next boot, the system will automatically create mount points in RAM for the main directories (/tmp, log, etc.), and it will run perfectly.
This was the main reason why, many years ago, I chose FreeBSD for almost all my embedded systems. Even today, on my Raspberry Pies, I keep the SD cards in read-only mode and use external storage in read-write mode. This ensures that, in case of an unexpected poweroff, the system will come back up, and there will be no wear on the memory card.
I already showcased a few immutable #Linux distros, but never quite explained what they are.
As a lot of people seem to think they’re the future of the Linux desktop, I feel differently. Let’s look at what these are, the advantages and the drawbacks:
@thelinuxEXP with #immutable#linux#distros, users cannot uninstall or replace default applications because they are installed as #readonly. For me, this is a limitation not a feature and thus I prefer #tradotional linux distros in order to customise my desktop environment to my liking.
