* build: use --runstatedir instead of --localstatedirAndreas Henriksson2017-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The util-linux code was previously aligned to use @localstatedir@ and the util-linux build system was set to override the default to use /run. Current GNU Coding Standards introduced the @runstatedir@ variable for this purpose. Lets use that instead. The GNU default for @runstatedir@ is ${localstatedir}/run so util-linux still override the default to be /run to preserve the status quo from before. The only difference is that you'll now pass --runstatedir to override the location on the command line instead of --localstatedir. (FWIW, Debhelper in compat 11 will automatically start passing --runstatedir=/run to all autotools configured builds. It already passes --localstatedir=/var (to avoid it ending up with the GNU default /usr/local/var) which breaks the util-linux build system code that tries to default it to /run. This change will thus allow util-linux and debhelper to work better together and avoid the need for a package-specific override.) Relevant historic commits: * commit 07a16b9d1e5a48550a0d19abb9a900853433ffa2 "build-sys: change --localstatedir to /run" * commit 80c51185d50f00a2701f9379f10fc48a0f885dfc "uuidd: use run configured state directory" * commit 01c5b787947aeaffc7e56000827e3edefa357c59 "agetty: use configured run state directory" [kzak@redhat.com: - add $runstatedir fallback for autoconf < 2.70 - check for unmodified $localstatedir] CC: Sami Kerola <kerolasa@iki.fi> Signed-off-by: Andreas Henriksson <andreas@fatal.se> Signed-off-by: Karel Zak <kzak@redhat.com>

* misc: update --help content againRuediger Meier2017-06-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We change -h, --help display this help and exit -V, --version output version information and exit to -h, --help display this help -V, --version print version Some thoughts about this: * use "display" for --help because it matches better if we would add pager support (like git --help) * "print" for --version to be different * "this" for --help is important to make clear that running --help would not give you any better information than the one you see already * remove "information and exit" because it's bloat for the short-help, everybody knows what it does if it exists In the manpages we should use the old, longer but more correct descriptions, inclusive a reminder if --help/--version are only working when used as the only option. Note the term "version information" indicates that we don't only print a single version number. CC: J William Piggott <elseifthen@gmx.com> Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>

* | libfdisk: fix NLS supportKarel Zak2017-04-251-2/+12
|/ | | | | | | | | | | | | | | | | | | The current libfdisk code uses gettext() to translate strings. It means it follows the default text domain (as set by textdomain(3) usually in the main program). This is useless for public shared library. We have call private bindtextdomain() and use dgettext() with private domain name to be independent on the main program. For this purpose include/nls.h supports UL_TEXTDOMAIN_EXPLICIT to use dgettext(). Note that libfdisk will continue to use util-linux.po, rather than keep the texts in the separate file. The nls.h has to be included only from fdiskP.h to be sure that nls.h works as expected for the library. Signed-off-by: Karel Zak <kzak@redhat.com>
* agetty: fix characters reorder in login promptKarel Zak2017-03-271-0/+4
| | | | | | | | | | | | | | The current agetty uses TIOCSTI ioctl to return already read chars from login name back to the terminal (without read() before tcsetattr() we will lost data already written by user). The ioctl based solution is fragile due to race -- we can return chars when terminal already contains another new chars. The result is reordered chars in login name. The solution is to use extra buffer for already read data. Reported-by: Michael Tretter <m.tretter@pengutronix.de> Signed-off-by: Karel Zak <kzak@redhat.com>
