Fedora 33 Problem

[Richard Kimberly Heck]

I upgraded to Fedora 33 yesterday, and since then LyX will not start if 
the user directory already exists and is on an NFS share. E.g.,

# lyx -userdir ~/files/lyx/

fails if ~/files/lyx/ exists and ~/files/ is an NFS mount. However, the 
same command succeeds if ~/files/lyx/ does not exist---it is created and 
populated as normal---and LyX is then able to open files on the same 
filesystem.

It seems to freeze in the call to

lockf(fd, F_LOCK, 0)

at filetools.cpp, line 1262, in fileLock (called from LyX::init).

Any ideas?
