lscpu currently prints information for CPUs configured in the system.
In case of KVM or other virtualized guest operating systems, this
refers to the virtual system, and bears no relation to the physical
topology of the system.
It would be useful if lscpu could also display the physical topology
info when available:
$ ./lscpu
Architecture: ppc64le
Byte Order: Little Endian
CPU(s): 16
On-line CPU(s) list: 0-15
Thread(s) per core: 1
Core(s) per socket: 1
Socket(s): 16
NUMA node(s): 1
Model: IBM pSeries (emulated by qemu)
Hypervisor vendor: KVM
Virtualization type: para
L1d cache: 64K
L1i cache: 32K
NUMA node0 CPU(s): 0-15
Physical sockets: 2 <<< New
Physical chips: 4 <<< New
Physical cores/chip: 4 <<< New
For now, physical topology information is available on platforms that
support the following RTAS (Real time abstraction service) call provided
by librtas:
rtas_get_sysparm(PROCESSOR_MODULE_INFO).
Currently this call is available to the PowerVM (pHYP) guests on PowerPC.
With a patch propoosed to PowerKVM, this RTAS call would also be available
to PowerKVM guests.

The iovec based solutions allow to send multiple strings by one

We need a better way, it seems that the original report is mostly
about udev rules disadvantages than about libblkid bug. See RH
bugzilla (#1172510) for more details.
The libmount provides way how to deal with parsing errors in fstab --
on error callback function is executed and according to the return
libmount manipulate with the malformed line, possible are three
states:
1/ fatal error; all file ignored (callback rc < 0)
2/ recoverable error; malformed line ignored (callback rc > 0)
3/ ignore the error (callback rc == 0)
The 2/ is the default if no callback specified.
Unfortunately our utils uses 3/. The correct way is to use 2/.

The current libmount version returns error when no able to convert
username/groupname to uid/git.
# mount mount /dev/sda1 /mnt/test -o uid=ignore
# mount: failed to parse mount options
This is regression, the original mount(8) has ignored possible unknown
user/group names and the option has been used unconverted (with the
original value). For example UDF kernel driver depends on this behavior
and "uid=ignore" (or "forgot") is a valid mount option.

To create more partitions, first replace a primary with an extended partition.
I knew I should have had two primary partitions available, but I did
not notice that the disk was seen as full (I was trying to grow it)
This change detects available primary partitions, and if so indicates
we are out of space, rather than out of partitions.

The function write_output() add additional \n after each message on
TYPE_TPC. This is required by syslog daemons, otherwise you will see
multiple log messages merged together in your log file, for example:

printf "AAA\nBBB\n" | logger -p info -u <any-socket>
Unfortunately, the connection initialization functions keep the
default ALL_TYPES as connection type and nowhere in the control struct
is info about the final real connection type. The problem is invisible
when you specify --tpc or --udp on logger command line.

https://rufus.akeo.ie/ This software has an extra format option for older BIOS.
With this fix the main partition is created with some alignments and for the
remaining unallocated space a small extra and empty partition with
identification 0xEA is created.
On the List of partition identifiers for PCs at
http://www.win.tue.nl/~aeb/partitions/partition_types-1.html is is said that
there is a freedesktop proposal to use also type ea as boot partition
Unfortunately the software fdisk (util-linux-2.27) can not classify that
partition. I send for the fdisk program my 2 patches so that fdisk recognize
this partition type.
