during configuration (after install) of Oracle XE 18c on my 16.04, I noticed this message generated by the shell script:
/bin/df: unrecognized option '--direct' 'Try '/bin/df --help' for more information.
I'm not sure how important it is for the install, the script goes on asking for the password to be set on system users...
ANYWAY the point for me it's that the --direct option is available on other linux versions, for example here, it seems to be part of the standard GNU utility, but I supposed that I've already got it as part of the Ubuntu 16.04 distro.
Anybody could please clarify this? Is there a way to obtain the same behaviour with my current version of df?
Thanks in advance.
