Overview
SmilartOS is a Linux operating system based on CoreOS (https://www.coreos.com/). There are differences between SmilartOS and CoreOS:
-
OS installation process
-
OS upgrade process
-
Default settings
-
Set of utils
-
SAM
You can use official CoreOS documentation to configure anything in operating system. SmilartOS doesn’t change any binary files in base CoreOS distribution. So SmilartOS is 100% compatible with CoreOS. This documentation describes differences between SmilartOS and CoreOS. You should use official CoreOS documentation for other questions.
Hardware requirements
SmilartOS has only one special requirement: at least 8 GB of RAM.
Other hardware requirements are the same as for CoreOS.
Installator always uses disk /dev/sda as a target disk for operating system. It can’t be changed. If you have several disks and not sure which is /dev/sda, disconnect all other disks except for one that will be used in operating system installation process. You can return other disks after installation completed.
