Because I started this topic, then I should clarify/state that Xfe (2.1.1+) is working with smb protocol

but not by default, it needs some other tcz (fuse3, gvfs) and configuration.
In summary, after I manage to have the win11 "windows shares" to be seen in the "host" linux (Arch linux type) then in a chroot I can see it also. So when Alpine linux runs in a chroot, I started xfe, and in left-side panel in tab "Places" (not tab "Tree"), down in section "Mount Points" it shows an item like "tmp@192.168.x.x.
My problem was that the "host" runs systemd services + wayland, and I need to have active processes running like gvfs-*(fuse, smb, ?) plus also to change
/etc/fuse.cfg to allow not-root users to see mounted devices. Then moreover, from the "guest" (Alpine in chroot) I need the proper access rights to "host"
/run/user/1000/gvfs (here is smb seen as mounted in host).
