See #3288 for the global overview. This ticket is similar to #4460, but to adapt remaining Techniques where porting to non-Linux is not trivial.
These Techniques include at least:

• ./techniques/applications/apacheReverseProxy/1.0/configuration.st
• ./techniques/applications/openvpnClient/1.0/openvpnClientConfiguration.st
  • Requires a "service started on boot" generic method
• ./techniques/applications/apacheServer/1.0/apacheServerConfiguration.st
  • Requires a "service started on boot" generic method
  • Requires OS-specific Apache configuration paths and tools like a2enmod
• ./techniques/systemSettings/process/servicesManagement/1.{1,2}/servicesManagement.st
  • Requires a "service started on boot" generic method
• ./techniques/systemSettings/networking/nfsServer/1.0/nfsServerConfigure.st
  • Requires a "service started on boot" generic method
• ./techniques/systemSettings/misc/clockConfiguration/1.0/clockConfiguration.st
  • Requires a file for timezone, specific to each OS (apparently?)

• techniques/systemSettings/remoteAccess/sshKeyDistribution/2.0/sshKeyDistribution.st
  • Uses "getent" to get a user's home directory, must change to use grep /etc/passwd (or "lsuser -a home" on AIX)

• userManagement
  • Uses adduser with specific options (or useradd?)
