This is a follow up question to this Q/A.
I tried the command on my laptop it worked:
setfacl -m 'u:programX:rwx' /etc/NetworkManager
I checked that my embedded device had
acl installed and marked correct.
But I'm finding when using the command on the embedded device I get
setfacl: /etc/NetworkManager: Operation not supported.
When I check
man setfacl my version of
acl seems to support the
acl on the device support the operation, when it works fine on my laptop?
