/*
|
|
* For the builtin FSMonitor, we create the Unix domain socket for the
|
|
* IPC in the .git directory. If the working directory is remote,
|
|
* then the socket will be created on the remote file system. This
|
|
* can fail if the remote file system does not support UDS file types
|
|
* (e.g. smbfs to a Windows server) or if the remote kernel does not
|
|
* allow a non-local process to bind() the socket. (These problems
|
|
* could be fixed by moving the UDS out of the .git directory and to a
|
|
* well-known local directory on the client machine, but care should
|
|
* be taken to ensure that $HOME is actually local and not a managed
|
|
* file share.)
|
|
*
|
|
* FAT32 and NTFS working directories are problematic too.
|
|
*
|
|
* The builtin FSMonitor uses a Unix domain socket in the .git
|
|
* directory for IPC. These Windows drive formats do not support
|
|
* Unix domain sockets, so mark them as incompatible for the daemon.
