Subject: mounts.nfs: v2 and v3 background mounts should retry when server is down.
X-Git-Tag: nfs-utils-1-2-6-rc7~5
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=bf66c9facb8e4798c79e1286e3da2dcafeed83fb

mounts.nfs: v2 and v3 background mounts should retry when server is down.

The point of background mounts is to have the mount
retried if the mount fails. This patch allows the v2/v3
background mount to proceed in the case when the server
is down by not making EOPNOTSUPP a permanent error.
