equery u docker
| Code: |
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for app-emulation/docker-19.03.12:
U I
- - apparmor : Enable AppArmor support.
- - aufs : Enables dependencies for the "aufs" graph driver,
including necessary kernel flags.
+ + btrfs : Enables dependencies for the "btrfs" graph driver,
including necessary kernel flags.
+ + container-init : Makes the a staticly-linked init system tini available
inside a container.
+ + device-mapper : Enables dependencies for the "devicemapper" graph
driver, including necessary kernel flags.
- - hardened : Activate default security enhancements for toolchain
(gcc, glibc, binutils)
+ + overlay : Enables dependencies for the "overlay" graph driver,
including necessary kernel flags.
+ + seccomp : Enable seccomp (secure computing mode) to perform system
call filtering at runtime to increase security of
programs

Ideas on what configuration is wrong? Thanks!
Should I use zfs as overlay as described in https://docs.docker.com/storage/storagedriver/zfs-driver/? |

| Your subject line says that Docker crashes on startup, but your post body makes no mention of any crash. The dmesg output may just be a general diagnostic, and not actually fatal. What do you see that makes you think Docker crashed? |

| That indicates the Docker daemon is no longer running as the pid that the service manager expected. You need to find the message(s) it wrote before terminating to see why it is not running. |
