<damex> hi, i just found out if file system on which vyos is located is 'corrupted' - it won't boot forcing you to manually run fsck from other system. let's say debian can do fsck on boot and recover your fs by itself but vyos lacks fsck in initramfs.
<damex> jjakob: i have been on last rolling releases. currently that box runs vyos-1.3-rolling-202003010958-amd64.
Didn't confirm it personally as I don't know how to test this or where to look for the initramfs fsck steps.
