looks like WSL does not support named pipes yet? dbus suffers and other apps do unless i force other forms of IPC!

Please fill out the below information:

• Microsoft Windows [Version 10.0.17134.648]

• What you're doing and what's happening:
  Trying to create named pipes with mkfifo seems to be not implemented:

• What's wrong / what should be happening instead:
  tipyng mkfifo test in bash gives error: Operation not permitted

• Strace of the failing command
  strace -o test.strace -f mkfifo test

WSL supports named pipes. If I had to guess (and I do, for lack of repro) you have done that mkfifo command with a relative path of ./test on DrvFs mounted without metadata enabled (which is the default). [ed: separately, dbus does not use named pipes but we digress.]

$ cd ~ && sudo umount /mnt/c
$ sudo mount -t drvfs C:\\ /mnt/c -o metadata
$ cd $(wslpath C:\\) && cd $(wslpath $(cmd.exe /c "echo %USERPROFILE%") | tr -d '\r')
$ mkdir ./pipetest && cd ./pipetest
$ strace -o test.strace -f mkfifo ./test
