RTFM sshfs(1) states:
MOUNTING FROM /ETC/FSTAB
To mount an SSHFS filesystem from /etc/fstab, simply use sshfs
as the file system type. (For backwards compatibility, you may also use
fuse.sshfs).
But creating an /etc/fstab entry and using mount does not work:
2025-05-02 19:07:12 admin@dq67sw ~
$ grep dpchrist /etc/fstab
dpchrist@samba:/var/local/samba/dpchrist /samba/dpchrist sshfs
noauto,uid=197609,gid=197121 0 0
2025-05-02 19:07:15 admin@dq67sw ~
$ mount /samba/dpchrist
mount: can't find /samba/dpchrist in /etc/fstab or in /etc/fstab.d/$USER
Comments or suggestions?
Unfortunately Cygwin hasn't integrated FUSE filesystem types into
'mount' and /etc/fstab. This is why FUSE mounts are recorded in
/var/run/fuse.mounts rather than in the usual mount table, for example.
The sshfs man page is correct for Linux and other OSs but less so for
Cygwin. On Cygwin any FUSE mount has a managing process; these are
sshfs, and when available, ftpfs, memfs, etc. They do the actual mount
and then hang around in background to support operations on the mounted
filesystem. The Cygwin DLL doesn't know about these filesystems.
If your goal is to have "permanently" FUSE-mounted filesystems, about
all I can suggest is to run sshfs from your first Cygwin shell after a
system boot.
