Perhaps this is what you meant: https://sources.debian.net/src/acl/ > # touch testfile > # setfacl -m u:nobody:w testfile > setfacl: testfile: Function not implemented Thanks for that. Running the above under ktrace(1), I can see that no ACL-related syscall is happening. ENOSYS is coming from either libacl or from a stub (unimplemented) function in libc. It is almost certainly the latter, because I don't see anything in libacl itself that would return ENOSYS: https://codesearch.debian.net/results/package%3Aacl%20ENOSYS Regards, -- Steven Chamberlain steven@pyro.eu.org
