Some issues on fresh installed Debian-Hurd
Hi, I installed a fresh Debian-Hurd using netinst-iso from http://ftp.debian-ports.org/debian-cd/hurd-i386/current/. Beside the kernel choice the installation went smoothly (a problem Debian-Hurd shares with Debian-kFreeBSD ^^). I had to modify line 117 in /etc/hurd/rc: settrans -c /proc /hurd/procfs --compatible - settrans -c /proc /hurd/procfs, otherwise the /proc file system didn't came up. That reduces the noise during boot dramatically (cannot stat /proc or something like that). But still (the VM is 06:03:47 up 3 days, 10:16) the console (xl vncviewer) doesn't come to a prompt. OpenSSH-Server runs, so I can access remotely. I'm quite unsure if it has to do with procfs or another issue (nothing suspicious in log or on screen) - but I'd like to mention it. The 3rd issue I recognize is an nfs failure: # mount -t nfs waldorf:/data/Projects /data/Projects $ cd /data/Projects/OSS/libstatgrab/hurd/ $ ../configure ../configure: error: cannot find myself; rerun with an absolute file name *** Error in `/hurd/nfs': double free or corruption (!prev): 0x002016c0 *** /data/Projects is gone (for protocol) Best regards -- Jens Rehsack rehs...@gmail.com -- To UNSUBSCRIBE, email to debian-hurd-requ...@lists.debian.org with a subject of unsubscribe.

Could you please double check that (e.g. update-alternatives --display runsystem should say /etc/hurd/runsystem.sysv). # update-alternatives --display runsystem runsystem - auto mode link currently points to /etc/hurd/runsystem.sysv /etc/hurd/runsystem.gnu - priority 5 slave halt: /sbin/halt-hurd slave reboot: /sbin/reboot-hurd /etc/hurd/runsystem.sysv - priority 10 slave halt: /sbin/halt-sysv slave reboot: /sbin/reboot-sysv Current 'best' version is '/etc/hurd/runsystem.sysv'. I cannot say why no proc was mounted before I removed --compatible when /etc/hurd/rc isn't used. But it works (proved by visual examination ^^) Maybe we should first check why /etc/hurd/rc is involved in boot-process?

Also, check that you have an entry like c:23:respawn:/sbin/getty 38400 console in your /etc/inittab to get a getty on the mach console (of course inittab is only used if you use sysvinit).

Hurd is not a kernel. There is no package hurd-1 or hurd-1.3.nnn.

I cannot say why no proc was mounted before I removed --compatible when /etc/hurd/rc isn't used. But it works (proved by visual examination ^^) Also, --compatible is a valid argument and it is recommended to use that for compatibility with Linux' /proc. There is no reason to believe it should cause any trouble. I cannot tell why it caused trouble - but now after I uninstalled gnumach-image-1.3.99-486 the issue disappears. Maybe we should first check why /etc/hurd/rc is involved in boot-process? Yes. Add exit 0 at the top. It is not used. Done without harming anything - seems to have a relation to gnumach-image-1.3.99-486 But still (the VM is 06:03:47 up 3 days, 10:16) the console (xl vncviewer) doesn't come to a prompt.

Apparently, 'c' is a valid identifier. If you have no getty for the console, please add it. ttyX is used when the Hurd console is running, 'console' refers to the mach console. Added and there is a login :) From original mail now only the nfs issue remains.

Hurd's mount simply does not work like Linux' mount. Our mount doesn't parse /proc/mounts. It should do so, if only to avoid this reoccurring confusion. BTW: why I initially assumed the is a problem with the way mounting /proc: # top Error, do this: mount -t proc proc /proc At this point, did you verify that /proc is mounted at all? But indeed: $ mount -t proc proc ./foo procfs: Too many arguments Try `procfs --help' or `procfs --usage' for more information. mount: cannot start translator /hurd/procfs: Translator died Finally there is something - even if I don't know what: # ls -l /proc | wc -l 75 # cat /proc/1/cmdline init [2] So it seems to me something what feels like a procfs is there - but what ;) But /proc/mounts doesn't show itself (what else could be missing?)
