The machine won't be rollbacked so that's not an issue. The reason for following this route is that it's faster than doing it from source (it's an old machine).

Follow-up question - /dev contains a /dev/concat/label entry - is this entry created when loader.conf invokes the kernel module? Yes. Many of the GEOM modules (label, mirror, concat, stripe, etc) create nodes in the relevant subdirectories in /dev as soon as they taste the drives (or other providers) and discover metadata belonging to them. This is generally when they are loaded (if modules) or at boot time (if compiled into the kernel or preloaded by loader.conf). Any time you insert a device (such as a USB stick) the loaded modules also have an opportunity to taste it and create nodes as appropriate. The machine won't be rollbacked so that's not an issue.

gconcat question
Dear mailing list, What are the steps to bring back gconcatenated disks if doing an upgrade from FreeBSD6 to FreeBSD7 like this? As-is situation: FreeBSD 6.2-STABLE ad0 has FreeBSD ad1, ad2 and ad3 are gconcatenated using 'gconcat label -v data /dev/ad1 /dev/ad2 /dev/ad3'. Planned upgrade: Reboot from cdrom, install FreeBSD7 from cd to ad0 /Roger ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
