I want a filesystem for data can be rebuild easily and is tolerant of inconsistency. Some examples will be web icon cache, remote data files, or ccache.

Best solution I ever had is ZFS with -o sync=disabled -o direct=disabled. But as you know ZFS is not exactly linux native and can be hard to install&update on some systems.

Some linux native solution I've think of include overlayfs with violate or LD_PRELOAD hooks. But overlayfs only stops fsync and not O_SYNC/O_DIRECT. And LD_PRELOAD dont works on golang and can be hard to configure in container workloads.

I want to do:

ip -4 rule add fwmark 123 table 123

ip -6 rule add fwmark 123 table 123

But in an single ip -batch.

I tried:

rule add from 0.0.0.0/0 fwmark 123 table 123

rule add from ::/0 fwmark 123 table 123

But it just add ipv4 rule twice. Confusing......

I know i can do it by ip -4 -batch && ip -6 -batch, but i think it should be an way to do it, as i can also add ipv4 and ipv6 route in an single batch.
