I'm an aged (over 30) OS enthusiast. Previously, as a developer in a small work group, I became the sysadmin by default since I was the only developer with a dozen users in a growing AIX environment.

Early Linux adopter, installing Slackware with 30+ floppies. I've installed most variants of Unix, Linux, Plan9, mkLinux, NeXtSTEP 486, BSD/386, NetBSD, FreeBSD, and I'm still waiting on HURD :)

Using Windows, I am limited by Windows. In Unix, I'm only limited by my knowledge of Unix.

comment Create a volume group from a logical volume instead of a physical volume
I don't agree that resizing is complicated or risky, assuming one has a current backup handy. Occam's razor is the principle I admin by, adding no more complexity than necessary. If one must configure a nested VG/LV, then there should be a good reason to do so (use case). In my experience I've found the greatest risk to data usually comes from human error, again: backup!

comment how to write dd command to replace backup image of root partition?
Can't do that using dd, you need something more selective like tar, zip or even cpio.

comment how to write dd command to replace backup image of root partition?
If I read your question correctly, it sounds like you wish to reinstall the OS and then reapply your configuration changes. If that is the case, you need only backup the few files you edited, reinstall the OS, and then carefully reapply your changes.

comment Can we add home partition by adding an additional hard disk?
That depends on the type of filesystem /home is on. You may have to move the data as outlined in one answer. You may be able to extend /home. What is the fs type of /home? Are you using LVM?

comment Is partition table type “loop” a good or bad idea on BTRFS?
Could you add the command you used to create the btrfs filesystem to your question? How many disks? RAID?

comment Is the EFI boot loader not in MBR?
The EFI boot loader is in its own partition, type EF00, formatted vfat. The EFI loader resides on the filesystem, but isn't necessarily in the first N blocks. What is it you want to do?

comment How to mount GPT nfts partition
You'll need to install the ntfs-3g package. Search for it in your system's packages (you didn't mention which distro/version).

comment Fedore 20 rescue mode from usb stick
You can use any live rescue cd, it doesn't have to be Fedora. /root isn't usually a partition (though it could be), likely a directory on /. You need to know which filesystem to mount, then mount it and clean it. SysRescueCD is fairly stable and robust.
