- Have `${DataDir}/bzzd.ipc` as IPC path default.
- Respect the `--datadir` flag.
- Keep only the global `--ipcpath` flag and drop the local `--ipcpath` flag
as flags might overwrite each other. (Note: before global `--ipcpath`
was ignored even if it was set)
fixes ethersphere#795
This commit adds a TOML configuration option to swarm. It reuses
the TOML configuration structure used in geth with swarm
customized items.
The commit:
* Adds a "dumpconfig" command to the swarm executable which
allows printing the (default) configuration to stdout, which
then can be redirected to a file in order to customize it.
* Adds a "--config <file>" option to the swarm executable which will
allow to load a configuration file in TOML format from the
specified location in order to initialize the Swarm node The
override priorities are like follows: environment variables
override command line arguments override config file override
default config.
