“Hey, server X’s /tmp is almost full. Do you know what’s up with that?” my coworker asks me.
“No idea.”
“Okay, I’ll call the application person and see.”
…Five minutes pass…
“So, can we start backing /tmp up?”
“Why? It’s /tmp. People do not, and should not, store important things there.”
“Yeah… this project’s software is keeping a copy of their important documents there.”
“Do they realize that tmpwatch removes things left idle more than 10 days?”
“Oh, crap….”
…Ten minutes pass…
“Can we shut tmpwatch down? It’s deleting this project’s data.”
ARGGGGGGGGGGHHHHHHHHHHHHHHHHHH.
