Netrunner Home

[solved] @ at the top of the partition?


#1

I installed netrunner in /dev/sda9, alongside with Mint which was already installed on another partition.

As netrunner couldn’t boot anymore, I decided to chroot to it from my Mint OS (boot Mint, mount /dev/sda9 and chroot to it) to see what’s in the logs.

To my surprise, I found that there is a “@” folder at the top of the partition :stuck_out_tongue: see trace below

The @ directory typically is an indicator for a snapshot created by the installer to boot the system from a btrfs partition.
