1. People that were using the in-kernel SMB server in Solaris or Windows.

2. Samba performance sucks (by comparison) which is why people still regularly deploy Windows for file sharing in 2025.

Anybody know if this supports native Windows-style ACLs for file permissions? That is the last remaining reason to still run Solaris but I think it relies on ZFS to do so.

Samba's reliance on Unix UID/GID and the syncing as part of its security model is still stuck in the 1970s unfortunately.

The caveat is the in-kernel SMB server has been the source of at least one holy-shit-this-is-bad zero-day remote root hole in Windows (not sure about Solaris) so there are tradeoffs.
