[Dump-users] Dump/restore directories' ACLs

[SZYMCZAK J. - E. Val./D. S. et Développement/P. i. <Jer...@de...>]

Good morning

We're looking for some help on dump/restore commands on our Ubuntu server

references :
Ubuntu 18.04 LTS x64, kernel 4.15.0-106-generic
dump:amd64/bionic 0.4b46-3

We can perform dump and restore commands on parts of our filesystem. 
Files, directories, Linux rights are correctly restored.

We've noticed a problem with Access Control Lists : files' ACLs are 
correctly restored, but not for directories.

Example of ACLs on a directory before dump :
/# owner: root//
//# group: ENTE-ENS/domain admins//
//user::rwx//
//user:20000:rwx//
//user:ENTE-ENS/jeremy.szymczak-smb:rwx//
//group::r-x//
//group:20000:rwx//
//group:ENTE-ENS/admins-xp-ens:rwx//
//mask::rwx//
//other::r-x//
//default:user::rwx//
//default:user:20000:rwx//
//default:user:ENTE-ENS/jeremy.szymczak-smb:rwx//
//default:group::r-x//
//default:group:20000:rwx//
//default:group:ENTE-ENS/admins-xp-ens:rwx//
//default:mask::rwx//
//default:other::r-x//
/
Example of ACLs after restore :
/# owner: root//
//# group: ENTE-ENS/domain admins//
//user::rwx//
//group::r-x//
//mask::rwx//
//other::r-x/

Command used to dump :
/dump -0 -A $PATH_ARCH/$BAK_NAME.arc -L "$BAK_NAME" -f /dev/st0 $SAV1 /
(the variables are correctly defined at the beginning of the script)

Command used to restore :
/restore -io -A $PATH_ARCH/$BAK_NAME.arc -f /dev/st0/
The same command without the -o option gives the same result.

Have we missed something in the dump/restore behavior ? Or in the 
parameters to use ?

Thanks a lot
