✨ cons.saver — bestie's guide to the console screen-saving icon 💅

okay so real talk, this is cons.saver, section 8 of the User Manuals, and she is literally a general-purpose Linux console screen save and restore server. no cap. she's the little helper who keeps your screen vibes safe 🫶

---

🌸 SYNOPSIS 🌸

cons.saver TTY

---

💖 DESCRIPTION 💖

so here's the tea: you invoke this helper program with the Ctrl-o key combination, and she saves and restores the user session on the screen. that's it, that's the whole gig. press the keys, she handles the rest, periodt. ✨

---

🎀 OPTIONS 🎀

• TTY — this is literally the only argument she takes, bestie. it's the TTY NAME from which the system will save and restore. one argument. no more, no less. she's lowkey a minimalist 👑

---

🔒 SECURITY 🔒

okay this part actually matters so pay attention 🙈

good news first: cons.saver does not need to be invoked by root. slay. 💅

but — and this is the important bit — she only needs read and write access to /dev/vcsa*, and that is a priviledged operation. so here's what you do:

1. create an unprivileged user 🧚
2. make cons.saver setuid to that user
3. assure that all the vcsa* are owned by that user too

that's the whole recipe. do that and she's set. skip it and... well, don't skip it fr fr 😭
