Subject: [PATCH 33/47] timedatectl: assert timezone is not null in setenv()
call.
setenv is declared as:
extern int setenv (const char *__name, const char *__value, int __replace)
__THROW __nonnull ((2));
And i->timezone can be NULL, if for example /etc/localtime is
missing. Previously that worked, but now result in a libc dumping
core, as seen with gcc 2.22, due to:
