pdm sync vs pdm install --frozen-lockfile

[deronnax]

Isn't pdm install --frozen-lockfile strictily equivalent to pdm sync? And if so, should not we remove --frozen-lockfile from sync, to avoid to have 2 ways of doing the same thing?

[frostming]

pdm install --frozen-lockfile may still update the pinned versions, but the updates won't be reflected in the lockfile. While pdm sync is guaranteed to be a lock-free operation that installs whatever in the lockfile.

You can try it yourself by doing some modifications to the pyproject.toml and run those commands
