This version brings bug fixes, enhancements and a new script utility,
scriptlive. For detailed information see the release notes:
http://www.kernel.org/pub/linux/utils/util-linux/v2.35/v2.35-ReleaseNotes
Pull some fixed applied after the release.
Disable the use of code under GPLv3 included in hwclock since v2.30. The
subject was discussed upstream[1] and it was decided that hwclock will
be made GPLv2-only again in v2.36, so do it in advance in Buildroot.
Meanwhile, be warned that all OS images selecting hwclock built with
Buildroot since commit 74235a6854
(util-linux: bump to version 2.30)
contain code under GPLv3, which imposes some technical difficulties to
include in embedded systems. For more information see GPLv3, Section 6,
"Conveying Non-Source Forms", and the definitions of User Product and
Installation Information[2].

Subject: [PATCH] libfdisk: add fdisk_set_disklabel_id_from_string()
|
|
|
|
We have fdisk_set_disklabel_id(), but it's old ask-API based function.
|
|
It's not comfortable if you want to avoid dialog or template.
