Initialize a new repository and working directory that shares its

history with another repository.

|
|
NOTE: using rollback or extensions that destroy/modify history
|
|
|
(mq, rebase, etc.) can cause considerable confusion with shared
|
|
|
clones. In particular, if two shared clones are both updated to
|
|
|
the same changeset, and one of them destroys that changeset with
|
|
|
rollback, the other clone will suddenly stop working: all
|
|
|
operations will fail with "abort: working directory has unknown
|
|
|
parent". The only known workaround is to use debugsetparents on
|
|
|
the broken clone to reset it to a changeset that still exists
|
|
|
(e.g. tip).
