The securelevel would normally prevent the deletion of a file.  The 
secure level of this jail is -1 in any case so the schg flag should be 
ignored. security.jail.chflags_allowed=0 seems to supersede the 
securelevel according to sysctl(8).

Some part of installworld is misbehaving in the jail. The security 
mechanisms in securelevel and security.jail.chflags_allowed are not working.
