Greetings

I'm trying to modify the vm subsystem using sysconfigdb.
In accordance with the man pages for stanza(4) and sysconfigdb(8)
I've created newconfig.vm.stanza as below. However, running

sysconfigdb -a -f newconfig.vm.stanza vm

returns

/etc/sysconfigtab: Unable to update file from /tmp/sysconfigtabAAAaaxvta:
Cross-device link. /tmp is a symlink to /local/tmp. Is that the problem,
or am I missing something else?

Regards,

Patrick O'Brien
