Thank you for the reply.  I vaguely remembered that the mount point must 
not exist prior to calling sshfs(1), and tried that permutation earlier, 
but it did not work.  It still does not work:

2025-04-22 20:07:20 admin AT dq67sw ~
$ sshfs dpchrist AT samba:/var/local/samba/dpchrist /samba/dpchrist

2025-04-22 20:07:38 admin AT dq67sw ~
$ echo $?
127

2025-04-22 20:07:45 admin AT dq67sw ~
$ cat /var/run/fuse.mounts
# Updated by FUSE apps; stale entries OK; DO NOT EDIT this binary file!
/home/admin/cvs-old sshfs 2627 
//toor AT cvs//var/local/cvs-old/dpchrist/.zfs/snap/sshfs/cvs/var/local/cvs-old/dpchrist/.zfs 
sshfs 2673 //toor AT cvs//var/local/cvs/sshfs/cvs sshfs 2031 //toor AT cvs//
/sshfs/f3 sshfs 2163 //toor AT f3//
/sshfs/samba/dpchrist sshfs 926 //dpchrist AT samba//var/local/samba/dpchrist

2025-04-22 20:12:39 admin AT dq67sw ~
$ ls -l /samba
total 0


Throwing various options at sshfs(1) makes me think it is brain dead (?):

2025-04-22 20:14:02 admin AT dq67sw /var/log
$ sshfs -d dpchrist AT samba:/var/local/samba/dpchrist /samba/dpchrist

2025-04-22 20:14:58 admin AT dq67sw /var/log
$ sshfs -d -f dpchrist AT samba:/var/local/samba/dpchrist /samba/dpchrist

2025-04-22 20:15:20 admin AT dq67sw /var/log
$ sshfs -d -f -o ssh_command=/usr/bin/echo 
dpchrist AT samba:/var/local/samba/dpchrist /samba/dpchrist

2025-04-22 20:16:40 admin AT dq67sw /var/log
$ sshfs foo bar --baz

2025-04-22 20:16:56 admin AT dq67sw /var/log
$ which sshfs
/usr/bin/sshfs

2025-04-22 20:17:57 admin AT dq67sw /var/log
$ file `which sshfs`
/usr/bin/sshfs: PE32+ executable (console) x86-64 (stripped to external 
PDB), for MS Windows, 10 sections
