Sudo is running as user root, according to whoami.
My home directory is NFS mounted. According to the Linux system
administrator here, root does not have superuser permissions on an
NFS mount. Consequently, root does not have permission to rename
a file in runtime/doc when runtime/doc was created by me under my
home directory with permissions 755:
drwxr-xr-x 2 gary swgroup 4096 Mar 8 16:41 runtime/doc
The system administrator says that this is normal, expected
behavior. However, it worked fine from March 8, 2016, through
January 30, 2017, and first failed on March 2, 2017. So something
changed between January 30 and March 2.
I tried to build and install Vim 8.0.271, the last version that
I installed without this problem, and it also failed with the same
error. So it does appear that it was this system and not Vim that
changed to cause the problem.
The problem can be fixed by changing the permissions on runtime/doc
to 755.
I'm working with the system administrator to find out what changed,
but I don't know that I'll ever find out.
Regards,
Gary
