Ubuntu Install & Swap & Partitions. I understand that the typical Linux kernel takes up about 1GB of RAM, so assume it will run easily in 2GB of RAM If your host station has 16GB or more of RAM, for most applications you really dont need any swap partition. I usually keep the /home/ on a different disk like the 1TB disk you have and all the rest is on the SSD drive. My typical setup is done using gdisk (not fdisk) root/os/SSD drive part1 : win fat32 of 512MB formatted for EFS ( this is eventually mounted under /boot/EFI/ ) part2 : /boot (if I have multiple versions or flavors of linuxes) on the same host part3 : / of linux-version-flavor-1 part4 : / of linux-version-flavor-2 part5... part6... partN: Perhaps SWAP if needed and on the 2nd disk just one huge /home/ Just make sure that the UID/GID's are the same across all the flavors of linux so that /home/ can be easily used on all versions without any issues Again this is an example you are free to choose what you want. I am a fan of hackintosh these days... but linux is still a passion Mayur On Fri, Mar 8, 2019 at 12:00 PM <discuss-request at blu.org> wrote: > Send Discuss mailing list submissions to > discuss at blu.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.blu.org/mailman/listinfo/discuss > or, via email, send a message with subject or body 'help' to > discuss-request at blu.org > > You can reach the person managing the list at > discuss-owner at blu.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Discuss digest..." > > > Today's Topics: > > 1.
