Dust off your Pi, drama’s booting
PiCore - Raspberry Pi Port of Tiny Core Linux
Teeny-tiny Pi OS is back: fans cheer, skeptics grumble about old docs and “bloated” rivals
TLDR: piCore brings Tiny Core Linux’s tiny, RAM‑only style to Raspberry Pi for fast, clean reboots. Comments range from praise for piCorePlayer and nostalgia to nitpicks about old docs and a fiery slam on heavier systems, sparking a lean‑vs‑convenient debate that matters for DIY builds and appliance‑style projects.
Tiny Core Linux’s Pi spin, piCore, is stealing the spotlight — and the crowd is loud about it. Fans gush that it’s ultra‑minimal and runs entirely in memory, meaning every reboot is a fresh, clean slate. One diehard shouts out piCorePlayer, saying this tiny setup is a dream for turning a Raspberry Pi into a serious music streamer. Nostalgia hit hard too, with commenters joking they’re dusting off long‑forgotten Pis from the closet.
Then the spice arrives. An eagle‑eyed reader calls out that the readme looks old (version 5.x), triggering the classic “is this actually up to date?” back‑and‑forth. And the hottest take? A commenter fires a shot at newer, heavier Linux approaches — calling them a “monstrosity” — while praising Tiny Core’s keep‑it‑lean philosophy. Cue the showdown: minimalists love the predictable, don’t‑break‑anything vibe; modernists want convenience and newer tooling.
Between laughs about “rescuing” Pis from storage bins and flexing how this OS won’t let you wreck your setup, the community’s verdict is clear: tiny, tidy, and fast. Want the philosophy behind it all? The devs point to their concepts page. Whether you’re building a music box or a DIY gadget, piCore is the small OS making big noise.
Key Points
- •piCore is a Raspberry Pi port of Tiny Core Linux designed by Robert Shingledecker and maintained by a small team.
- •piCore runs entirely in RAM with a default Cloud Mode that mounts downloaded extensions read-only and does not persist changes.
- •Mounted Mode provides persistence via a second ext4 SD card partition for extensions and backups, with configurable backup/restore.
- •Installation uses raw SD card images written with dd (Linux) or Win32 Disk Imager (Windows); a wired Internet connection is recommended.
- •The first SD card partition (VFAT) holds boot files and remains unmounted during operation; users can expand the second partition and filesystem using fdisk and resize2fs.
