/dev/log isnt a device. its created by syslog to capture messages that programs send to.
And I was wondering if mknod has a hidden mode or something like that - /dev/log is the only "pink file" (ls colour) on my fs.
to chroot syslog, wouldnt you need to adjust the path and recompile all programs that call syslog()? sys/syslog.h: #define _PATH_LOG "/dev/log"
Yes, that could definately be a problem. Most programs do not log to syslog at all, or do they? Recompiling some programs shouldn't be that much of a problem - just very much time consuming...
If / and /usr/jail are on the same physical partition, maybe you could hardlink.
A hardlink seems to have worked! Having disabled klogd I was able to get a glimpse at why syslog-ng doesn't seem to be working. Libsafe 2.0 gave throw stuff at my console, syslog-ng segfaults. If I call syslog-ng with -u 102 -g 19 it segfaults, if I call it with -u syslog -g syslog it shows me the help screen (i figure it doesn't understand syslog and wants it numeric). If I call it without u and g it starts but gives configuration errors (yeah I know, I need to edit the config file ;).
Interested if you get anywhere with this... incidentally, is syslog going to be running as root in the chroot? I dont suppose it has >to...
I created user and group syslog and let syslog 2.5.6 switch to them as well as chrooting to /usr/jail/syslog. Don't think I'm paranoid ;=) I'll keep you up-to-date with that and I will mostlikely be writing a small syslog-ng in chroot once I've got that done and release v 0.3 of my Linux Distro (with syslog-ng chrooted of course ;). - Kaladis
Can you move the device file over to /usr/jail/syslog/dev/log and symlink it from /dev/log? That way, programs can still find it (if they don't care about a symlink), but it's living beneath the syslog-ng root.

Dear Mailinglistpeoples,
First of all I'd appreciate it if you could cc all replies to kaladis@gmx.de since I'm not a member of this mailing list.
I am trying to run syslog-ng chrooted - to be accurate, from /usr/jail/syslog. I created /usr/sbin/syslog-ng, created all directories and so on, copied the needed libraries etc. Syslog-ng is starting quite fine within that chrooted environment as user syslog group syslog. However it is not logging anything. I guess that it must have to do with /dev/log since that isn't accesiable out of that environment anymore. Now I'm asking myself how I could have /dev/log under /usr/jail/syslog/dev/log or what else the problem could be.
Thanks for your help
