Of co= urse we also can think of additional knobs, but there is an issue - it wo= nt help just to exclude some files, the additional features also do sit i= n the code, so the replacement stubs will be needed, also testing them al= l over will take some time.

ZFS it self, reserves something like 3.5 mb of space in the ZFS partition, for boot code. This is how we boot ZFS on MBR. It should be possible to use this on GPT as well, we just don't. --=20 Allan Jude --jKq7lTugEKOxx1Be45NUqqRP4mBNFAhm1-- --kfVhP3nkvOrUhIQ18gFcEwjwW9V09DtDI Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQIcBAEBAgAGBQJYi4OwAAoJEBmVNT4SmAt+2MYQAJD7HB6pRurs975TyFxEkNcn ypb8Wm5+8ZagMXnktGKJDrDNgZ4vPvI6+IQ/rSt1+vmkEIsBQtcXb8LZAGapftb1 8Ic/mTJpesHTJj3FCtkM7qbr8SlspNBSDFKGi67kV2GrUmYQi4fb+Jn3I3RerI7E mWU1O4CygAlp+FobzWlqqBC6+6+Eti/3CcvEDrAEk12O6+gP6HpOywM2cHWSqgvA bn3jgX4tmc35zssfeFuToilc1B7pkvadFHV5ZGhIaOe1/MchO7oEI6aBP/lhRlV2 UcbS/yVd3Y4EN54ixa1uEZh7DRlpIR4f5xU+aDZPMeJBC2EpEthlVYBxdsxkcLLP FQDbfggNQPaB4xi84nCyICDoXkHmpXdURXmanP7qnc3l+Vdj9sMvk5AEM/gyIypB tKexwc7lcUFUL0LZjosU2wAD/92SojJ534YlfUQcPcochULZFOS8TFQ46xsy0aU5 cMToxclJDciBYJrHcBFaJjBSS/Tohcy/W5Rw8pvUb9KRdfE+1OR6V+sZzWfYiBPd L/oFJv96UmAC+c5M6IAH54mQaquIlnjVG21uzuLyr2fZni2sOTMN6uQsEg/bT4oI pmXSgjf9HzDMpKpRQ/sPsHMOTkkeJIBt6cDUXRh62ANROpYDEHZI49HyKhnFUt/J IVZrhSqi3bmRXIdN2viq =r5/z -----END PGP SIGNATURE----- --kfVhP3nkvOrUhIQ18gFcEwjwW9V09DtDI--
