Description Trix Farrar 2005-06-14 16:20:19 UTC

According to documentation, multiple filesystems can be specified on a single line in /etc/exports.  However, when more than one filesystem is specified on a single line, mountd emits an error to syslog and does not export either filesystem.  syslog message is; "bad exports list line" followed by the filesystems specified.

Fix: 

exports(5 and Chapter 23.3 in FreeBSD Handbook should be updated to reflect current behavior of mountd(8), unless it would be easier/better to change mountd(8)'s behavior back to match documentation.
How-To-Repeat: In my case, /usr/ports and /usr/src are different filesystems.  These filesystem are exported from machine willow to machines spike, harmony, and dawn.

In file willow:/etc/exports:
/usr/ports -maproot=0 spike, harmony, dawn
/usr/src -maproot=0 spike, harmony, dawn

Filesystems are exported correctly.

Edit willow:/etc/exports to contain:
/usr/ports /usr/src -maproot=0 spike, harmony, dawn

Signal mountd with:
# kill -s HUP `cat /var/run/mountd.pid

tail /var/log/messages to find
