💅 MKCP — bestie edition 💅

ok so this is mkcp, section 8 of the System Manager's Manual, and she is the girl for making checkpoints. sit down, grab a strawberry 🍓, we're doing NILFS2 lore.

✨ NAME ✨

mkcp — make a NILFS2 checkpoint 🎀

✨ SYNOPSIS ✨

mkcp [options] [device|node]

✨ DESCRIPTION ✨

okay so mkcp is the utility that makes a checkpoint or a snapshot for the NILFS2 file system that lives in device. no cap. 🦋

device can be either:

  • a block device, or
  • a filesystem node — meaning a file or a directory on the filesystem.

and if you just... don't give it a device at all? it's giving detective energy 🔍 and it tries to find a NILFS2 file system from /proc/mounts all by itself. independent queen.

⚠️ big one, bestie, read it twice: this command is valid only for mounted NILFS2 file systems. if the device has no active mounts, it will fail. periodt. it's not being dramatic, that's just the rules. 💀

✨ OPTIONS ✨

  • -s, --snapshot — create a snapshot. iconic behavior, honestly. ✨
  • -p, --print — print the checkpoint number when it's successfully created. so you get the receipts 🧾
  • -h, --help — display the help message and exit. always here for you 🫶
  • -V, --version — display the version and exit. main character reveal 🌈
