Summary: rsync -A drops mask from ACL
Product: rsync
Version: 3.0.6
Platform: Sparc
OS/Version: Solaris
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: way...@samba.org
ReportedBy: bugzi...@baldwin.users.panix.com
QAContact: rsync...@samba.org
CC: bugzi...@baldwin.users.panix.com
rsync is supposed to preserve ACLs with the -A option. However, rsync 3.0.6
does not preserve ACLs, as it drops the "mask" portion of the ACL. wayne said
on the mailing list:
Rsync was of the belief that a mask was only needed if an ACL had named
values, otherwise it tried to simplify the ACL to mask off the group
mode and dropped the mask. I've checked in a change that makes it keep
whatever mask value is specified, so the ACLs should be identical now.
This will get released in 3.0.6.

However, this has not been done. Example (performed as root):
# rsync --version
rsync version 3.0.6 protocol version 30
