Re: how make the debian bootable
Dear all
Thank you for your help
Let me explain
I am testing how to duplicate the system and have fast
recovery in case of any problem
1/ I install the debian and all programs in /dev/hda
2/ then i put the new harddrive in /dev/hdc
3/ format, partition as hda and mount /dev/hdc
4/ using tar to copy all file system except /proc...
from the hda to hdc
5/ shutdown the computer, change ide cable (unplug the
hda, plug hdc to hda)
In above steps, It should not need to change any
/etc/fstab or grub and it should be fast recovery
I know I miss some steps about boot but not sure how
to do it.
Any idea
Thank you
