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. Regards, Jason
