I have the exact same question except not with regards to labels but toggling TRIM capability on the root filesystem. - Start system - At loader, boot single-user (option 4) - At prompt choose /bin/sh - mount -a - tunefs -t enable /dev/ada0s1a --- fails - sysctl kern.geom.debugflags=16 - tunefs -t enable /dev/ada0s1a --- works - tunefs -p /dev/ada0s1a -- shows TRIM enabled - reboot - Boot into single-user, multi-user, whatever - tunefs -p /dev/ada0s1a -- shows TRIM disabled -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, US | | Making life hard for others since 1977.
