Also, there is a way to save/apply ACLs as well (using getfacl/setfacl). I've been using a variant of this script to save all ACLs into a script when backing up, just in case the backup approach doesn't save them (e.g., I typically limit my use of ACLs to XFS, because xfsdump preserves them, but just in case I use something that cant').
Of course, another option instead of using my script (but is more Linux- centric, not sure if it's SUS v3 / POSIX 100x-2001 compliant, let alone it probably doesn't work on other UNIX flavors) is to just use the "getfacl/setfacl" commands directly -- not only for ACLs, but regular UNIX permissions as well.
E.g., $ getfacl -R /abspath > /abspath.acls # Saves UNIX+ACL to file $ setfacl --restore=/abspath.acls # Restores UNIX+ACL from file
My older scripts for ACLs were designed for cross-Linux/Irix with XFS. This seems to work on Linux (I haven't tried older Irix versions), and possibly any UNIX post-SUSv3/POSIX100x-2001.
