Core File System Damage

[TomTravis]

after working for sometime with some Dev tools my chroot became unstable, no bash shell , Enter-chroot would not mount the systems tree, after fsck it became worse, Permission changed on the file system, had to remount exec. The files looked fine, could be libs were changed

core cmd chroot bullseye works however no bash still. I had a core system tar archive, This was written over the chroot.

The chroot came alive again, /lib /bin had new trees

It working again, I now create archive from Cron daily
