Sure they can , at least = for the time beeing, and we will=20 continue to use them. But innovation is desirable.=20 Systemd might be a terrible implementation or not (I dont know, I dont = use it) but the ideas behind it are sane.=20 rc systems are indeed robust, but they should be ancient history. They = are nothing but glorified autoexec.bat systems. Modern OSes need sophisticated dynamic service management systems, fault = management, transactional OS configuration databases, centralised event systems supporting kernel = sources.=20 This is the problem domain things like sytemd and dbus are tring to = solve. They might doit the wrong way, I personally think the direction Solaris took to solve some of those problems is the way to = go, but at least they are trying to do something, and=20 they clearly explored the problem space. Meanwhile here, some engineers are trying to change the FreeBSD OS = configuration to a new DSL, but without any consideration for issues of centralising OS databases and add innovation like transactions = and full concurrency safety.=20 YOu gotta ask yourself, since it is only a language change, why even = doit ????? It adds no technical innovations, the new=20 systems are not well enough thought out to support technical = innovation added incrementally later. So why are they doing it ? To change the DSL only ? By now all BSDs user are familiar with all = adhoc databases the OS offer. We are familiar (experts, even) with=20 the language they use. Changing this language , when no technical = innovation is present, is , in my opinion, ill-advised.=20 It is change for the sake of change, it is change because =E2=80=9Csomeone= wrote the code=E2=80=9D, not because it solves any real problem , or is = a well thought out engineering solution. I really hope someone from the = developers wakes up and vetoes those changes for the sake of change, like Junipers libxo, and attemtps to change the DSLs for the sake of = changing the DSL. > On 08 Jan 2016, at 17:20, Peter Beckman wrote: >=20 > On Thu, 7 Jan 2016, Dmitry Sivachenko wrote: >=20 >>=20 >>> On 07 Jan 2016, at 05:12, Mark Heily wrote: >>>=20 >>> On Sat, Jan 2, 2016 at 8:42 AM, Jonathan de Boyne Pollard >>> wrote: >>>>=20 >>>> I recommend, to anyone going down this route, looking towards = finishing >>>> systembsd, especially instead of inventing a wholly new suite of = protocols. >>>>=20 >>>> * https://uglyman.kremlin.cc/gitweb/gitweb.cgi?p=3Dsystembsd.git >>>> * >>>> = http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/debian-systemd-p= ackaging-hoo-hah.html >>>> * https://news.ycombinator.com/item?id=3D10176275 >>>>=20 >>>> The reason is that finishing systemdbsd will make happy all of the = people >>>> who want the desktop environments whose design is driven largely by = Linux to >>>> work on FreeBSD/PC-BSD.
