Public bug reported:
Binary package hint: grub2
(yes, package not installed, I removed it after it bricked my system)
Due to incessent boot and driver issues I converted my ubuntu system to
run in a chroot jail.
the next apt-get dist-upgrade bricked my system by installing grub on
the host drive.
Normally you would think, ok it boots the guest kernel and this can be
fixed from within.
However, in this case, / wasn't the root of any partition so it could
not boot.
Since grub-install was root, it could have checked for this
straightforwardly:
int check_for_root()
{
int fd1, fd2;
struct stat st1, st2;
fd1 = open(".", O_RDONLY, 0);
chdir("/");
if (chroot("/etc")) return 3;
stat(".", &st1);
stat("..", &st2);
if (st1.st_dev == st2.st_dev) {
if (st1.st_ino == st2.st_ino)
return 2; /* REAL ROOT */
return 0; /* CHROOT */
}
return 1; /* CHROOT ON MOUNTPOINT (probably safe to run bootloader) */
}
