Description

"vbird1" is a test account

  • Your Windows build number: (Type ver at a Windows Command Prompt)
    17046

  • What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)
    touch acl_test1
    setfacl -m u:vbird1:rx acl_test1

  • What's wrong / what should be happening instead:
    setfacl: acl_test1: Operation not supported

  • Strace of the failing command, if applicable: (If some_command is failing, then run strace -o some_command.strace -f some_command some_args, and link the contents of some_command.strace in a gist here)

Research direction

Start by reproducing the listed touch and setfacl commands in WSL and inspect the supplied strace, especially the getxattr and setxattr calls returning EOPNOTSUPP. Trace how WSL handles POSIX ACL extended attributes and define completion as making the reported ACL operation behave as expected, with regression coverage for this command sequence.
