I've been running lvm2 rootfs on amd64 and recently updated to openrc and bl-2. after fixing an lvm2 utils bug i was going about trying to update my initrd using the lvm2create_initrd script from redhat's cvs but the script doesn't work with baselayout 2 and openrc.

Code:
midas ~ # ./lvm2create_initrd -c /etc/lvm/lvm.conf
lvm2create_initrd -- make LVM initial ram disk /boot/initrd-lvm2-2.6.25-gentoo-r3.gz

lvm2create_initrd -- finding required shared libraries
lvm2create_initrd -- calculating initrd filesystem parameters
lvm2create_initrd -- calculating loopback file size
du: cannot access `(0x00007fff3a9fe000)': No such file or directory
du: cannot access `(0x00007fffc6dfe000)': No such file or directory
lvm2create_initrd -- making loopback file (6244 kB)
lvm2create_initrd -- making ram disk filesystem
lvm2create_initrd -- mounting ram disk filesystem
lvm2create_initrd -- adding required /dev files
./lvm2create_initrd: line 374: /dev/MAKEDEV: No such file or directory
lvm2create_initrd -- ERROR adding /dev files


code from the script.
Code:
# Add some /dev files. We have to handle different types of MAKEDEV invocations
# here, so this is rather messy.
RETCODE=0
echo "$cmd -- adding required /dev files"
verbose "BASICDEVICES: `echo $BASICDEVICES`"
verbose "BLOCKDEVICES: `echo $BLOCKDEVICES`"
[ "$VERBOSE" ] && OPT_Q="-v" || OPT_Q=""
case "$MAKEDEV" in
debian)
    (cd $TMPMNT/dev; /dev/MAKEDEV $OPT_Q $BASICDEVICES $BLOCKDEVICES)
    RETCODE=$?
    ;;
redhat)
    (cd $TMPMNT/dev; /dev/MAKEDEV $OPT_Q -d $TMPMNT/dev -m 2)
    RETCODE=$?
    ;;
gentoo)
    (cd $TMPMNT/dev; /usr/sbin/MAKEDEV $OPT_Q $BASICDEVICES $BLOCKDEVICES)
    RETCODE=$?
    ;;
*)
    echo "$cmd -- ERROR: $MAKEDEV is not a known MAKEDEV style."
    RETCODE=1
    ;;
esac
 
 
if [ $RETCODE -ne 0 ]; then
   echo "$cmd -- ERROR adding /dev files"
   cleanup 1
fi


I could create the initrd with baselayout 1 and i understand that a lot of important devices are moving to sysfs. Anyone have suggestions for updating the lvm2create_initrd script to work with baselayout 2 and openrc? openrc and baselayout 2 do work with lvm2 rootfs but the initrd needs to function as well.

mtab shows:

What's rootfs?


rootfs is where / was mounted for the kernel to boot
/dev/root is where / *may* have been relocated later.

Most distros filter out rootfs. Gentoo used to as well, but now we cannot as some users like to overmount / with tmpfs (which does require a kernel patch) and requires this is not filtered out.

The defalt lvm2 stuff works with OpenRC on my laptop. It works for others too.
However, you're also not the first to say it's not working, but as yet no-one can tell us why.
I'm also not that knowledgable about lvm myself so can't really help too much :/

It may have been a premature assumption that baselayout 2 did not require makedev without considering how udev would function with the new rc system. I can only assume that the bl-2 and openrc system or a recent udev build depreciated MAKEDEV. Since the makeinitrd script uses makedev to populate /dev when creating the ramdisk what does udev now use for this task?

udev has always used it's own special blend of voodoo ;)

Since my last reboot the "* Caching service dependcies ..." thing is extremely slow. It appears before every service, sometimes twice or more it takes about one minute to boot where it took some seconds before. I neither know why this problem is there nor how to fix it.

You could search this thread and see that something in /etc has an mtime in the future which causes the deptree to rebuild as it's always out of date.

After upgrade to openrc I am not sure how to configure vpn.

Here is sample from conf.d/net.example:

modules="iproute2 openvpn wpa_supplicant"
tuntap_tun0="tun"
config_tun0="192.168.1.1 peer 192.168.1.2"

and when I start it, the result is:
avk init.d # /etc/init.d/net.tun0 restart
* Bringing down interface tun0
* Destroying Tun/Tap interface tun0 ... [ ok ]
* Bringing up interface tun0
* Creating Tun/Tap interface tun0 ... [ ok ]
* 192.168.1.1 ... [ ok ]
* pointopoint ...
* nothing provides `peer' [ !! ]
* 192.168.1.2 ... [ ok ]
* Running postup ...
avk init.d #


looks like the syntax for 'peer' is gone, same about this syntax:
config_tun0="192.168.1.1 pointopoint 192.168.1.2"

I just recently upgraded to Baselayout 2 and OpenRC, and it seems to have broken things even though I ran etc-update and dispatch-conf. When I boot, it mounts the /dev filesystems, goes to wait for uevents, then directly enters runlevel 3, and then goes directly to login. This is without mounting the filesystem read-write or anything.

The weird part is this:
Code:
# rc-update show               
                  gpm |      default                 
                  xdm |      default                 
                 dbus |      default                 
                 fsck | boot                         
                 hald |      default                 
                 mtab | boot                         
                 root | boot                         
                 sshd |      default                 
                 swap | boot                         
                acpid |      default                 
                cupsd |      default                 
                local |      default nonetwork       
              dnsmasq |      default                 
           vixie-cron |      default                 
              sensord |      default                 
             iptables |      default                 
            syslog-ng | boot                         
           consolekit |      default                 
           localmount | boot                         
            pydoc-2.5 |      default                 
          consolefont | boot                         
              modules | boot                         
               esound |      default                 
             hostname | boot                         
               net.lo | boot                         
             net.eth0 |      default                 
               procfs | boot                         
               sysctl | boot                         
              urandom | boot                         
             cpufreqd |      default                 
         termencoding | boot                         
             timidity |      default                 
              hwclock | boot                         
             bootmisc | boot                         
        device-mapper | boot                         
           irqbalance | boot                         
            alsasound | boot
I had to run this in the login ZSH in order to finish setting up the services, and it worked:
Code:
# for i in `rc-update show | awk -F'|' '{print $1}'`; /etc/init.d/$i start
What went wrong here? I've even tried removing and re-adding the services above to no avail.

Have you checked whether rc_parallel="YES" or "NO" in /etc/rc.conf?

Both /etc/conf.d/rc and /etc/rc.conf have it set to NO.

What's really weird is that if I use that Awk script to start the services, they aren't stopped at boot. It simply exits the shell then goes to "remounting /".

You should delete the /etc/conf.d/rc after checking that you have any extra lines you may want from it transferred to /etc/rc.conf.

It has to be in the settings somewhere, I would check, and then re-check, all the settings in any boot 'rc' files, then make sure there is nothing left over from the old boot system causing this due to incompatibility issues.

You did follow the Baselayout and OpenRC Migration Guide, didn't you?

Yes, I did follow that guide. I've checked, and all of the settings from /etc/conf.d/rc were migrated correctly.

How would I know what to look for as far as old files causing trouble?

Today I've updated to openrc.
The first thing I noticed - I am using a read-only root setup however the "ro" in fstab seems to be ignored because / is now mounted rw after boot. I have to manually remount it as ro...
Bug? Change in configuration?

Any idea why a dependency like "before net" is not observed when starting the firewall? The firewall starts after all net.* services are running - not very secure, is it?
Also, the firewall (Firehol in this case) starts very-very slow compared to any other service. It was significantly faster before OpenRC :(

Another weirdness is that sometimes OpenRC says at shutdown "Caching service dependencies..." and tries to stop services that were not started at all, for ages!

Firehol starts considerably faster if the net.* services are constrained not to start in the boot runlevel through "coldplug" (whatever that is). But even so, the net.* services keep starting before the firewall (all of them in the default runlevel) 8O

I've tried all this with "rc_depend_strict" set both to YES and to NO.
Should a bug report be filed?

dcpcd times out when connecting via wep. Worked fine before. It works fine when I turn encryption off at the router. I tried connecting via Network Manager and the regular startup scripts. My /etc/conf.d/net:
modules="iwconfig"
key_g2="s:wepsux"
I am using the iwl4965 wireless driver via kernel 2.6.24-tuxonice-r3.
I upgraded a lot of packages, I tried to see if it was another packages fault. I downgraded to stable dhcpcd, didn't upgrade kernel and symlinked the kernel sources to the same as the kernel I am using. The only other package I can think of to check is the iwl4965-ucode & dhcp which were not upgraded.
Any suggestions?

You should filter out your wireless interface service in /etc/rc.conf:
Code:
rc_plug_services="!<wireless_service_name_here>"

This will prevent the service being started at boot runlevel. See if this solves the issue (provided that you have the service listed in the default runlevel).

Mistery solved: the process that rebuilds dependencies runs all config() sections of all services. Why is that?

Regarding the OpenRC's mistake to start the firewall after the network interfaces, how can I investigate the cause? The firewall service has among its dependencies "before net", "rc_parallel" is set to NO, "rc_depend_strict" is set to YES, net.lo is started in the boot runlevel, while net.eth* are started in the default runlevel, together with the firewall.

Help, Roy... :cry:

I just migrated to openrc. I did dispatch-conf, updated config files, including /etc/conf.d/net Now I have two problems.

1. /etc/init.d/net.eth1 which is my internet connection is starting up and everything seems to be OK (no errors). It is set to config_eth1="dhcp". After boot my resolv.conf is empty. I need to manualy restart net.eth1 and after that I have resolv.conf filled with proper dns servers and internet connection is working. What is going on??

2. My system was set to UTF (my locales are pl_PL.UTF8). Before openrc I had everything working ok. Now, the problem is that I can see letters specific to my language (ąćę) in terminal, but I can't write them. keyboard layout is pl. rc.conf UNICODE="YES". Again - what should I doublecheck?

Best Regards,
m.s.w

Try this in /etc/rc.conf:
Code:
rc_plug_services="!net.eth1"

or more general
Code:
rc_plug_services="!net.*"


I very much suspect there's something wrong with "coldplug" initiated services in terms of needed depndencies. Before baselayout-2 I never had the network interfaces started at boot runlevel.

Is there any real explanatory document on OpenRC and its configuration ? Roy himself admitted here that the comments in rc.conf are far from the actual subtleties :?
I also strongly recommend the Gentoo developers to think twice before unmasking beta versions of critical packages such as baselayout. I'm using ~arch packages for years now and I don't remember anything more problematic than OpenRC.
Lucky me, I took advantage of the unlucky experience of people who upgraded before me.

THank you, I'll try it when I have access to my computer. Still it is strange becouse I have coldplug=NO (switched off).

Another question is how to give up on openrc? Will it be enough to emerge -C openrc && emerge previous_version_of_baselayout, and then restore config files?

Best Regards
