When trying to create an FTP user with a home directory named
d'irectory it fails with the error:
Error: SysUser::update() failed: Unable to create system user: Unable to execute usermng: usermng: Command line argument number 3 is unsafe
This is software issue PPA-2351. FTP user whose home directory contains apostrophe cannot be created on a Linux service node.
This issue is planned to be fixed in future Plesk Automation updates.
