I believe this is happening cause the following call to mount in the
automount code is not locking updates to /etc/mtab correctly:
daemon/automount.c:243: if ( spawnl(LOG_CRIT, PATH_MOUNT, PATH_MOUNT, "-t", "autofs", "-o",
options, our_name, path, NULL) ) {
This is running on a Redhat 6.0/Kernel 2.2.12-SMP/autofs-3.1.3-2/mount-2.9o-1.
The machine is a Dual CPU PIII.
My temporary fix was to stick a sleep 2 between calls to automount in
the startup script /etc/rc.d/init.d/autofs.
But it really seems like there is a nasty race condition in
mount. Has anyone else seen a similiar problem?
Thanks very much for any help!
