But that probably can be worked around. It would be good to have *dm use a statically allocated VT. Otherwise if you have a need to change the number of getty's then you may end up conflicting with a running *dm until the next reboot.

RAID would probably have more potential to improve the speed, system boot scripts don't tend to do much CPU use. CPU speed is also increasing faster than hard disk speed, so the dependency on drive speed will probably become more of an issue. Last time I did some tests on Linux software RAID I found that it was lacking in this regard. I would have hoped to see some read benchmarks showing that a RAID-1 with two disks is nearly twice as fast as a single disk, however I didn't find any test that showed such a result or anything close to it. Optimising the read performance of Linux software RAID is one thing that can be done to improve such things (and generally improve all Linux performance).

I don't think that anything more than restarting *dm should be needed for such a change. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
