In my sole opinion the Linux community appears to have a change-for-change-sake fetish. This is entirely appropriate for an experimental project. The mistake that I made many years ago was inferring that Linux was nonetheless suitable for business. To experimenters a ten year product cycle may seem an eternity. To many organisations ten years is barely time to work out all the kinks and adapt internal processes to automated equivalents. And the smaller the business the more applicable that statement becomes. I do not have any strong opinion about systemd as I have virtually no experience with it. But the regular infliction of massively disruptive changes to fundamental software has convinced us that Linux does not meet our business needs. Systemd and Upstart are not the cause of that. They are symptoms of a fundamental difference of focus between what our firm needs and what the Linux community wants. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail Do NOT open attachments nor follow links sent by e-Mail James B.

Windows has had a fairly disruptive set of changes in Windows 10. About the only things that don't change are industrial OS's. When it comes to breaking user space, there's explicit rules against that in Linux kernel development. And internally consistent API/ABI stability is something you're getting in CentOS/RHEL kernels, it's one of the points the distributions exist. But the idea that Windows and OS X have better overall API stability I think is untrue, having spoken to a very wide assortment of developers who build primarily user space apps. What does happen, in kernel ABI changes can break your driver, as there's no upstream promise for ABI compatibility within the kernel itself. The effect of this is very real on say, Android, and might be one of the reasons for Google's Fuscia project which puts most of the drivers, including video drivers, into user space. And Microsoft also rarely changes things in their kernel, so again drivers tend to not break. -- Chris Murphy ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I haven't used the "allowdupe" option, so I don't know if it works for

user { 'user1':
uid => 1000, gid => 2000, ...,
allowdupe => true

Re: [CentOS] PUPPET - group IDS
I'm not familiar with the syntax you're using but the below worked for me using
'puppet apply grp-usr.pp' on my laptop where grp-usr.pp contained:
group { 'poc':
ensure => present,
gid => '1002'
}
user { 'one':
ensure => present,
uid => '1005',
gid => '1002',
require => Group['poc']
}
user { 'two':
ensure => present,
uid => '1006',
gid => '1002',
require => Group['poc']
}
The run produced no errors and
grep poc /etc/group
produced:
poc:x:1002:
with
egrep 'one|two' /etc/passwd
producing (with a couple of extraneous entries):
nobody:x:65534:65534:nobody:/nonexistent:/usr/sbin/nologin

[CentOS] nameserver issue
Hi all! This question is, at best, somewhat peripheral to Centos, but I'm hoping to be forgiven, and that someone here can give me a clue. I've just brought up a nameserver on my household LAN, bind9 on a Raspberry Pi. The connection with Centos is this: my main desktop is C7, and its hardwired network is also manual, not dhcp. I've edited the ipv4 config (in NM) and changed the DNS settings from 192.168.2.1 (the router) to 192.168.2.2 (the RPi). I've also manually tweaked /etc/resolv.conf to contain 192.168.2.2 instead of 192.168.2.1. works fine. until I fire up a vpn. having done that, looking in /etc/resolv.conf (while the vpn is connected) it has reverted to 192.168.2.1. after shutting down the vpn, 192.168.2.1 remains in resolv.conf what am I overlooking here? now the not-so-Centos-related question: I've changed the dhcp settings in my router so it should deliver 192.168.2.2 to the dhcp clients instead of 192.168.2.1. And it does, sorta. all the systems that use DHCP, now are configured with two DNS server addresses, 192.168.2.2, and 192.168.2.1. And I have no clue why 192.168.2.1 is still showing. Both windows and Linux systems are showing this behavior.
