so, everything looks fine!
we can chroot into this jail and test basic things out:


meena at beastix ~> sudo chroot /isolates/pkg-auto-remove-bug/root
root at beastix:/ # su -
root at beastix:~ # logout
root at beastix:/ # exit

cool. sh works, su works, let's remove ""unneeded"" packages:

meena at beastix ~> sudo pkg -r /isolates/pkg-auto-remove-bug/root autoremove

and try again:

meena at beastix ~> sudo chroot /isolates/pkg-auto-remove-bug/root
root at beastix:/ # su -
ld-elf.so.1: Shared object "libbsm.so.3" not found, required by "su"
root at beastix:/ #

we just broke a jail that was working perfectly fine a second ago.
