Hi Lennart,
My hope is that one day we can ship a read-only root dir by
default, or more specifically a btrfs file system with three
subvolumes in it: one read-only one mounted to /, and two
writable ones mounted to /home and /var, with /tmp mounted from
tmpfs.
I can see the motivation for having root be read-only if you *aren't*
using btrfs, but if we have a btrfs subvolume for the rootfs which is
snapshotted every time we perform a package/admin operation (and
perhaps also just on regular intervals for good measure), what would
we then gain by adding a read-only rootfs to the mix?
Thanks,
- Chris.
