Arch has a limited form of rebasing: "tla update".

It doesn't apply to a branch (i.e. a set of consecutive patches), but to
a single patch (the patch corresponding to the local uncommitted
changes), so it's a degenerate form of rebasing.

"tla update" basically did:
- save local changes as a patch in some temp-file.
- fetch&apply changes from the specified branch.
- apply the previous saved patch.

Rebasing does the same but with a set of patches:
- revert the set of patches.
- fetch&apply changes from the specified branch.
- re-apply the set of patches.
