Sun Solaris 10 3/05 accepts a boot parameter boot -verbose that boots the system with verbose messages enabled.
How do I persist this setting so that I do not have to type it at boot time ?
Example screenshot:
You can try with eeprom command to set the verbosity of boot output. Exec:
eeprom verbosity?=max
and reboot the machine to check. Beside max you can set debug level of verbosity. For more information you may refer man page of eeprom
verbosityparameter. However the workaround iseeprom boot-args=-v. – mvanle Jan 17 '22 at 09:50
