Re: disklabel change?

[Patrick Welche <prlw1%welche.eu@localhost>]

In fact, the difference is between "-t" and "-rt":

$ disklabel -t sd0
perc|Automatically generated label:\
        :dt=SCSI:se#512:ns#32:nt#64:sc#2048:nc#2143360:\
        :su#4294967295:\
        :pa#20971520:oa#264192:ta=4.2BSD:ba#0:fa#0:\
        :pb#33554432:ob#21235712:tb=swap:\
        :pc#4294703103:oc#264192:\
        :pd#4294703103:od#0:\
        :pe#4240177151:oe#54790144:te=4.2BSD:be#0:fe#0:
$ disklabel -rt sd0
perc|Automatically generated label:\
        :dt=SCSI:se#512:ns#32:nt#64:sc#2048:nc#2143360:\
        :su#4294967295:\
        :pa#20971520:oa#264192:ta=4.2BSD:ba#0:fa#0:\
        :pb#33554432:ob#21235712:tb=swap:\
        :pc#4294703103:oc#0:\
        :pd#4294967295:od#264192:\
        :pe#4240177151:oe#54790144:te=4.2BSD:be#0:fe#0:

Given

$ sysctl kern.rawpartition
kern.rawpartition = 3

I deem "-t" output to be correct (and matches what I had in /etc/diskpart)


Cheers,

Patrick
