6.2 File System Access
The ZENworks Agent runs as
root
. This provides it with the file system access required to perform
its management functions on the device.
On managed devices, do not mount the following directories over NFS:
/etc
,
/opt
,
/usr
,
/home
,
/
var
, and
/root
. The ZENworks Agent (zmd) is not designed to work with these directories
mounted over NFS, so this configuration is not supported.
6.3 Using the Software Updater, Installer, and
Remover from Users’ Managed Devices
The ZENworks Linux Management Software Updater, Software Installer, and Software Remover
applets are components of the desktop that work through the ZENworks Agent.
In ZENworks Linux Management, these three easy-to-use desktop applets provide users with the
ability to update existing software, install new software, remove existing software from their
managed devices, and view and edit system preferences. These three desktop applets replace the
user interface clients used in previous versions of ZENworks Linux Management. Software Updater,
Setting Description
max-cache-age Defines the number of days the contents of the cache are retained, after
which the contents are deleted. The default is 30 days. If this setting
specifies 0 days, the cache content never expires.
The cache cleanup is enforced on client startup and refresh. The contents of
the cache are sorted by date (oldest to newest) and deleted by applying the
max-cache-age setting, starting with the oldest content.
To change the max-cache-age setting from the default of 30 days to 60
days, for example, you enter the following command from the managed
device:
rug set max-cache-age 60
cache-max-size-in-mb This setting is only enforced at cleanup time; not during bundle download.
The default is 300 MB. If this is set to 0, there is no limit to the size of the
cache; however, the
max-cache-age setting still applies.
If the cache size exceeds the maximum size specified with this setting, the
cache contents are sorted by date and the oldest contents are deleted until
the cache size is within the specified size limit. If this size limit is exceed
while downloading bundles, the bundle contents are downloaded; however,
the next time the device restarts or refreshes, the cache is cleaned until its
size is within the specified size limit. The cache cleanup process will not
delete files downloaded within the last 24 hours to get within the specified
limit.
To change the cache-max-size-in-mb setting from the default of 300 MB to
500 MB, for example, you enter the following command from the managed
device:
rug set cache-max-size-in-mb 500
