A web search on the 'mount_nfs.so: undefined symbol: auth_put' turned up the
bug-report and fix:
https://bugs.mageia.org/show_bug.cgi?id=6903
The fix is basically to revert a change that was made going from version 5.0.6
(which is what is running here) and 5.0.7 (which is what you've got). The above
url links to the following page that shows the change:
ftp://ftp.kernel.org/pub/linux/daemons/autofs/v5/patches-5.0.7/autofs-5.0.6-fix-libtirpc-name-clash.patch
So to revert the change, one would edit the file 'lib/rpc_subs.c' in the source
distrib, and comment-out the code:
---
#ifdef WITH_LIBTIRPC
#undef auth_destroy
#define auth_destroy(auth) \
do { \
int refs; \
if ((refs = auth_put((auth))) == 0) \
((*((auth)->ah_ops->ah_destroy))(auth));\
} while (0)
#endif
---
thus (am not assuming you don't already know some/all of this kind of stuff):
===
/*
#ifdef WITH_LIBTIRPC
#undef auth_destroy
#define auth_destroy(auth) \
do { \
int refs; \
if ((refs = auth_put((auth))) == 0) \
((*((auth)->ah_ops->ah_destroy))(auth));\
} while (0)
#endif
*/
===
; and do leave single blank line above and below (not required from a technical
point of view).
Then recompile autofs like you did before, and see how it goes. If it all goes
well then one would need to determine if there are any unwanted side-effects
from commenting out that code.
However, before going this edit/recompile route, it would be good if you could
do the few tests in the earlier email today and from last night, with the
currently-installed autofs.
