in 2013 "remove overlayroot completely from cloud-initramfs-tools" https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=732788 overlayroot useless without kernel module overlayfs
The situation has changed in the meantime: /lib/modules/5.10.0-9-amd64/kernel/fs/overlayfs/overlay.ko I'll be happy to test, it should be easy as overlayroot has not changed in 9 years: https://github.com/larsks/cloud-initramfs-tools/tree/master/overlayroot if I wget/install from ubuntu's repo, it works. https://packages.ubuntu.com/impish/overlayroot ps - there is bilibop-lockfs, but it does not work with nfs, which is a solution for netbooting diskless clients. Which is what I am doing. "This package can be used as an alternative to fsprotect or overlayroot," https://packages.debian.org/stable/bilibop-lockfs bilibop-lockfs tries to determine the block device / is mounted on, and doesn't accommodate nfs. overlayroot works because it -o move whatever is mounted. Given it fails for the nfs case, should I file a bug against bilibop-lockfs docs? -- Carl K
