System

The system name must be compliant with the encoding rules for host name as per DNS RFC 1123. The DNS host name encoding rules are:

Characters have to alphanumeric or hyphen.

The name cannot start or end with a hyphen.

The name cannot start with a digit.

The number of characters has to be 63 or less. (Currently the system name length is limited to 32 bytes).

Image upgrades could cause the system to boot with an older system name format that is not DNS compliant. To prevent problems with dynamic DNS after an image upgrade, the system name will automatically be converted to a DNS compliant system name.

The rules of conversion of older system names are:

If the length is greater than 63 then the string is truncated. (This will not happen since the system name is anyway limited to 32 bytes)

All invalid characters at the beginning or end of the string are replaced with the character 'X'.

All other invalid characters are replaced with hyphens.
