# `Mob.DNS.Seeder`
[🔗](https://github.com/genericjam/mob/blob/master/lib/mob/dns/seeder.ex#L1)

Serialises `Mob.DNS.resolve/1`'s writes to `:inet_db`'s runtime host table.

Replacing one host's entry is a read-modify-write spanning several
`:inet_db` calls, so two resolves sharing an address would otherwise drop
each other's names. A locally registered process is the lock: `:global.trans/3`
keys its release on the node name captured at acquire time, and `Mob.Dist`
renames the node when it starts distribution after boot, which leaves that
lock held forever. Started on first use and unlinked, because `mob` has no
supervision tree of its own and a resolve from a screen callback must not tie
the seeder's life to that screen.

# `child_spec`

Returns a specification to start this module under a supervisor.
