christopherco diskutils: Add partprobe after partition creation (#725)
Latest commit 44d2261 Mar 18, 2021 History 
* diskutils: Add partprobe after partition creation

There can be a timing issue where partition creation finishes but the
devtmpfs files are not populated in time for partition initialization.
So to deal with this, we call partprobe here to query and flush the
partition table information, which should enforce that the devtmpfs
files are created when partprobe returns control.

* diskutils: invoke partprobe with flock

Added flock because "partprobe -s" apparently doesn't always block.
flock is part of the util-linux package and helps to synchronize access
with other cooperating processes. The important part is it will block
if the fd is busy, and then execute the command. Adding a 5 second timeout
to prevent us from possibly waiting forever.

* diskutils: Update timeout variable name

* diskutils: clarify debug log message

* Add parted to documentation and quickstart runner
