Description
System update hung at upgrading keybase
```
Setting up keybase (4.2.1-20190718132443.117e8ce562) ...
Restarting existing root redirector.
```
`ps ax` showed
```
31772 ? SN 0:00 lsof /run/user/1000/keybase/kbfs
31773 ? DN 0:00 lsof /run/user/1000/keybase/kbfs
```
Being blocked in uninterruptible sleep. Apparently due to my system having defined a NFS mount that was not available.
Suggestion: consider if it's possible to add the `-b` (_avoid blocking_) option for `lsof` calls.

Research direction
Start by locating the installer or upgrade path that invokes lsof while setting up the existing root redirector. Reproduce the hang with an unavailable NFS mount if possible, then verify that the upgrade no longer blocks in this situation and that normal Keybase setup still completes.
