.Sh DESIGN NOTES

Administrator have to be aware that non-jailed users

can kill processes owned by the same UID that are

running in jail environments.  It is suggested that

the administrators do not create user accounts outside

the jail enviornments with the same UIDs as the accounts

inside the jail.  Exactly same problem exists with file

system objects and this can't be sloved in this way,

because no information about jail exists in file's inode

and users outside of jail are not chrooted.

If administrator is running virtual servers with jail and

with regular users inside those virtual servers, it is

recommended that there should be no users accounts on this

machine outside the jail environments.

This above is an expected behavior.
