* Update autoconfig files to work with v2.71NeilBrown2022-06-071-3/+2
| | | | | | | | | | | | | | | | OpenSUSE recently updated autoconf to v2.71, and nfs-utils now doesn't build. This patch fixes it - mostly. This patch is the result of: - running autoupdate on configure.am and aclocal/* - removing any sections add that say they can safely be removed - revertion the change to AC_PREREQ. I haven't confirmed that it still works with v2.59. It does seem to work with 2.69 at least. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Steve Dickson <steved@redhat.com>

* Detect version of libblkid and act accordingly.Neil Brown2007-05-031-0/+20
libblkid earlier than 1.40 has a memory leak bug that make it unsuitable for use in mountd. So detect the version and default to not using it if too old. Give appropriate warnings in various cases.
