We switched Fedora to do vos release via ssh with localauth in I56ecdb2511597197deeeadf51f50da7e02f56954 and it has been working. Switch the rest of the update scripts. There is an increasing amount of common code, start a common functions.sh script where we can put this. Change-Id: I4ba6d64a84bb66e8686901b16010352de942f303

# Consider the case of a large mirror pulse (perhaps a new distro

|
# release is included, etc.). The "Last Update" time on the volume
|
|
# will indicate when this run finished.
|

#
|

# The last 15 minutes of that run could have brought in a significant

|
# amount of data. Now we move onto the next mirror pulse, and the
|
|
# "vos release" below will try to sync the remote R/O volume from
|
|
# "Last Update - 15 minutes" to now(). If you include the data from
|
|
# this pulse, we are now dragging across potentially *a lot* of data;
|
|
# enough to make the whole thing timeout. Then the volume is locked,
|
|
# and we keep putting more data ontop with each cron run making it
|
|
# even worse.
|
|
#
|
|
# By sleeping here for 15+ minutes and doing a trivial write, we can
|
|
# ensure that when the *next* release says "sync from Last Update - 15
|
|
# minutes" it will *only* include this trivial write, and not
|
|
# potentially this entire mirror pulse data too.
