Linux-to-Linux permissions, group ownership and ACL's

[JS761 (JS)]

In regard to the ignorePerms option, I found an answer here:

[v0.8.10] Ignore Permissions

Version 0.8.10 includes a new “Ignore Permissions” flag per repository. The primary use case is for filesystems that do not support permissions, such as FAT, or environments where changing permissions is impossible. When the checkbox is checked for a given repo files originating from this node will be announced with the “no permission bits” flag. Other nodes will use whatever their default permission setting is when creating the file. Nodes running older versions than 0.8.10 will use the permis…

I’m still not 100% sure what Syncthing does in Linux-to-Linux sync with ACL’s and group sticky bits.

My guess is that when ACL’s and group sticky bits are set on all devices, we can use the ignorePerms option to make those things entirely control the file permissions and group ownership.

However, I have read a number of statements like this one: Sync file ownership, and permissions - #2 by calmh

Permissions are synchronized. Owner and group would require running as root; this is neither recommended nor supported right now. There would be a bunch of corner cases to solve in that case as well…

That makes it sound like Syncthing cannot do what I am asking. Hence confusion.
