I have the problem similar to one described in 20071024 UPDATING.
The build is running inside a jail. The system is 6.2-RELEASE. I
supped this moring. I have the correct lib/Makefile. During
installworld I receive an error:
install: /lib/libc.so.6: chflags: Operation not permitted
*** Error code 71
Stop in /usr/src/lib/libc.
My situation is different in the libc is erased in the process.
Copying the new libc.so.6 from /usr/obj does not fix the problem.
Any ideas?
Sounds like kern.securelevel is in the way. See security(7).
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.
I should add that 'systcl security.jail.chflags_allowed=1' allowed
installworld to proceed without error. That solves my immediate problem.
There appears to be a bug in the security mechanism.
Later,
Jason
