Bug#676604: nfs-kernel-server: fails to start if exports are only defined in /etc/exports.d/*.exports
Package: nfs-kernel-server
Version: 1:1.2.6-2
Severity: important
After upgrading nfs-kernel-server, it fails to start, complaining that there are no exports.
service nfs-kernel-server start
Not starting NFS kernel daemon: no exports. ... (warning).
I do not have any changes to /etc/exports, it is true, but do have exports
defined in /etc/exports.d/*.exports, and these are valid exports.
By commenting out the check for an empty /etc/exports (introduced to resolve
#673798) in /etc/init.d/nfs-kernel-server, nfsd starts and all is well again:
if [ -f /etc/exports ] # && grep -q '^[[:space:]]*[^#]*/' /etc/exports
This check should probably be either be reverted, or it should at least iterate
it through all the /etc/exports.d/*.exports files before deciding there are no
exports.
live well,
vagrant
