# Mentalnet GNU/Linux
|
||
|
||
A light, TTY-only GNU/Linux distribution for 90s Intel Pentium-class
|
||
(i586) machines, built with [Buildroot](https://buildroot.org).

|
||
|
||
The ISO is a live CD: the entire system runs from the CD with a
|
||
read-only root filesystem, and the same CD carries a built-in hard
|
||
disk installer (`mentalnet-install`).
|
||
|
||
## Current release
|
||
|
||
**R1 "FirstStorm"** — named after DECO*27's
|
||
*Chūlán ~First Storm~* (初嵐～First Storm～).
|
||
|
||
## Versioning
|
||
|
||
- Major releases bump the `R<n>` number (`R1`, `R2`, ...).
|
||
- Minor releases keep the `R<n>` base version and use the codename as
|
||
the minor version.
|
||
- All codenames are taken from Vocaloid, Hatsune Miku or Kasane Teto
|
||
songs.
|
||
|
||
| Release | Codename | Song | Notes |
|
||
|---------|----------|------|-------|
|
||
| R1 | Mesmerizer | *Mesmerizer* — 32ki (Hatsune Miku & Kasane Teto) | Initial release |
|
||
| R1 | **FirstStorm** | *Chūlán ~First Storm~ (初嵐～First Storm～)* — DECO*27 | **Current** — swap-free installer, true i586 support, terminal/input hardening, interrupt-storm fixes |
|
||
|
||
## Quick facts
|
||
|
||
| | |
|
||
|---|---|
|
||
| Login | `root` / `mnlinux` |
|
||
| Hostname | `mentalnet` |
|
||
| Kernel | `6.12.104-mentalnet-intel32` |
|
||
| Media | Live CD with built-in installer |
|
||
| CPU | i586 (Pentium / Pentium MMX) or any newer x86 |
|
||
| RAM | 128 MB minimum (64 MB usually works) |
|
||
|
||
## Security after install
|
||
|
||
The default root password is **`mnlinux`** — please change it after
|
||
installing:
|
||
|
||
```
|
||
passwd
|
||
```
|
||
|
||
Then, for day-to-day use, create a regular user and give it sudo
|
||
privileges (sudo is included in the build):
|
||
|
||
```
|
||
adduser myuser
|
||
```
|
||
|
||
You have two options to grant sudo:
|
||
|
||
- Add the user to the `sudo` group, which the shipped sudoers file
|
||
already trusts:
|
||
|
||
```
|
||
addgroup myuser sudo
|
||
```
|
||
|
||
- Or, if you prefer the classic `wheel` group, enable it with
|
||
`visudo` (uncomment the `%wheel` line) and add the user to it:
|
||
|
||
```
|
||
visudo
|
||
addgroup myuser wheel
|
||
```
|
||
|
||
**Verify that sudo works for the new user before locking root** —
|
||
log in as the user and run, for example, `sudo ls /`.
|
||
|
||
Once sudo is confirmed working, lock the root account so it cannot
|
||
be accessed (SSH included):
|
||
|
||
```
|
||
passwd -l root
|
||
```
|
||
