Following up on that 'ottomh', seems that sysd wants symlink - e.g. : http://www.freedesktop.org/software/systemd/man/localtime.html https://bugzilla.redhat.com/show_bug.cgi?id=885246 http://www.linuxfromscratch.org/lfs/view/7.6-systemd/chapter06/glibc.html ISTR that it (commonly) used to be a symlink, years ago, and then (commonly) changed to being a file - maybe re what partitions are available at boot, &c. Some googling might help nail it down better - e.g. https://bugzilla.redhat.com/show_bug.cgi?id=91228 &c&c. hth, akh -- -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
