Bug#948584: libc6: Mounting nfsv4-export from my NAS there is a segfault in libc
Package: libc6
Version: 2.29-8
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Trying to mount a nfsv4-export from my NAS using systemd.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Therefore I'm no programmer, I tried to file a bugreport.
Just tried to configure the path.mount Config-files and tried to mount them.
* What was the outcome of this action?
No Mount was possible. In the first phase I got Failures with
"option"-Problems,
not being precise enough what option was bad. Then rpc-bind problems. And at
last
the segfault failure of libc.
* What outcome did you expect instead?
Just being able to mount and use the nfsv4-exports.
