http://reboot.pro/topic/14547-linux-...m-and-boot-it/ (http://reboot.pro/topic/14547-linux-load-your-root-partition-to-ram-and-boot-it/)
That above is where I learned from. I had only negligible modification which is
Code:
mount -t tmpfs -o size=100% none ${rootmnt}
changed to:
Code:
mount -t tmpfs -o size=50% none ${rootmnt}
It is because my RAM is 64GB, I limited my system root to use up to max 32GB only. On fresh boot starting firefox and huge virtual machine it ate 10GB
Code:

What I removed and did not show here is my SSD mounts, they are RAID 0 4SSDs striped very fast for my huge data also. Winchester HDD are for backups, also removed from the above not shown.
Microshits I dumped entirely for almost 20 years. Never look back.
