It seems like this check should treat append-only files as read-only, only failing to open them if write access is requested, rather than failing all the time like it does now.
fs/nfsd/vfs.c:nfsd_open() refuses to open append only files.
Append-only is an unsupported concept in the all existing revisions of
the NFS protocol. In fact, NFS has no support for append writes at all:
they have to be emulated by the clients.
In this particular case, I'm not using append-only files, but rather using immutable files and append-only directories to create an archival space where things can be added but not changed. Even if the protocol can't deal with append-only regular files, isn't it possible to allow mkdir but not rmdir?
