package/util-linux: bump to version 2.35 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]. 1. https://lore.kernel.org/util-linux/20200127202152.4jh2w4chch37wgee@ws.net.home/T/#t 2. https://www.gnu.org/licenses/gpl-3.0.html Signed-off-by: Carlos Santos <unixmania@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

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.
