Boot parameters (kernel parameters) are used to influence the MiniOS boot process. Some of them are common to all Linux distributions, others are specific only to MiniOS. You can use them to disable a desired type of hardware detection, to start MiniOS from a hard disk, etc. To use the options with syslinux, press Esc to activate the boot menu while MiniOS is running as usual, and when you see the boot menu, press Tab, edit the boot options, then press Enter. For grub, press E to edit, then F10 to boot. A command line will appear at the bottom of the screen, at the end of which you can edit or add new boot parameters. Some grub parameters cannot be changed interactively. To change them, edit boot/grub/grub.cfg.
| Option | Value | Example |
|---|---|---|
| from= | Load MiniOS data from a specified directory, device, or even an ISO file. | from=/minios/ from=/Downloads/minios.iso from=http://domain.com/minios.iso from=/dev/sr0/minios from=/dev/disk/by-label/MyFlash/minios from=ask from=ask/customdir |
| load= | Enable loading of certain .sb modules specified as a regular expression. | load=00-core load=core,minios,kernel,firmware load=00,01,02 load=00-03 |
| noload= | Disable loading of certain .sb modules specified as a regular expression. | noload=05-xfce-apps noload=xfce-apps,firefox noload=05,06 noload=04-06 |
| nosound | Disable sound at startup (used only in the Fluxbox environment variant). | nosound |
| perchdir= | Select a profile or perform an action with a profile. Can take as a value the profile number or the values resume (resume previous session), new (start new session), ask (select session at startup). If the perchdir option is missing, the loading will be performed in "clean" mode. | perchdir=1 perchdir=resume perchdir=new perchdir=ask perchdir=/dev/sda1/changes perchdir=/dev/disk/by-label/MyFlash/changes perchdir=askdisk perchdir=askdisk/customdir |
| perchsize= | The size of the DynFileFS virtual file system, which is used to store data on non-Linux file systems such as FAT32 and NTFS. By default, a 16 GB file system is created. If your disk is smaller, you should specify the required size in MB in the bootloader configuration file. | perchsize=4000 perchsize=32000 |
| dynfilefs | Force DynFileFS permanent change files even on Linux filesystems. | dynfilefs |
| toram | Activate the copy to RAM function. | toram |
| text | Disable X startup and remain only in text console. | text |
| debug | Enable debugging when starting MiniOS. | debug |
| nozram | Disable zram swap. | nozram |
| zramsize= | Specify zram swap size in MB. | zramsize=512 zramsize=2048 |
| zramcomp= | Specify zram compression type. For Debian 12, the available options are: lzo lzo-rle lz4 lz4hc zstd, default is lzo-rle. | zramcomp=lzo zramcomp=lz4 |
| root_password= | Root user password. | root_password=toor |
| user_name= | User name. If you specify the user name root, then the user profile will not be created, the user_password parameter will be ignored. In the current version, this parameter can be equal to either root or live. | user_name=live |
| user_password= | User password. | user_password=evil |
| host_name= | System host name. | host_name=minios |
| default_target= | Systemd target. You can learn more about systemd targets here. | default_target=graphical default_target=multi-user default_target=rescue |
| enable_services= | Enable services at boot. | enable_services=ssh,firewalld |
| disable_services= | Disable services at boot. | disable_services=docker |
| ssh_key= | Name of the ssh public key file that must be located in the system folder on the media (along with the main .sb modules). By default, the system looks for a file named authorized_keys. | ssh_key=my_public_keys |
| scripts= | Scripts are launched when reaching multi-user target (init 3). To run scripts, they must be located in the minios/scripts folder. The scripts variable can be equal to true or false. By default, when scripts are found in the specified folder, the system launches scripts in alphabetical order in interactive mode on tty2. If the default target is graphical, the desktop environment is started, you must manually switch to tty2 with Ctrl+Alt+F2 to observe the script execution. With scripts=false, scripts are not loaded even if they are located in the scripts folder. | scripts=true scripts=false |
| cloud | Special mode for running as a cloud-init host. | cloud |
| hide_credentials | Hide credentials displayed as a hint in the console when starting the system. | hide_credentials |
| autologin= | Enable/disable automatic login to the system. Enabled by default. | autologin=true autologin=false |
