I’m on fedora 30 with everything to the latest(docker is 19.03.0-rc2) as of this topic, and when i get to the bootstrapping step, it fails and says that my filesystem is unsupported, so i investigated the source code and found out that overlay2 is indeed supported.. so i ran the offending line on my terminal and up to no avail, no regex was matched at all.. offending command(without the -q flag): > docker info 2\> /dev/null | egrep ‘^Storage Driver: (aufs|zfs|overlay2)$’ > No output from terminal However, upon removing the empty string match(^) It works perfectly and matches my Storage driver: > docker info 2\> /dev/null | egrep ‘Storage Driver: (aufs|zfs|overlay2)$’ > Storage Driver: overlay2 Why’s the case? Thanks and i can provide any other info if needed! ---

Can you paste the output of `docker info` here? I think they changed formatting on the 19.X version. ---

Looks like there is a Server entry at the top level, and now Storage driver is a second level entry, which broke our regex. I found this when running docker unstable, but didn’t dig further. I will fix this tommorow. ---
