The only thing in OpenRC that creates the /etc/mtab file, and this is if it already exists as a file, is the mtab service script. If /etc/mtab doesn't exist, it is created as a symlink. Is something else on your system writing /etc/mtab as a file? Easy to ask, hard to asnwer. How do I find out? (In reply to William Hubbs from comment #2) > The only thing in OpenRC that creates the /etc/mtab file, and this is if > it already exists as a file, is the mtab service script. If /etc/mtab > doesn't exist, it is created as a symlink. I just noticed that the script doesn't consider the posibility of /etc/mtab being a symlink already. It's gonna print the warning even on systems where /etc/mtab is a symlink. So at least that part is broken. (In reply to Nikos Chantziaras from comment #4) > I just noticed that the script doesn't consider the posibility of /etc/mtab > being a symlink already. It's gonna print the warning even on systems where > /etc/mtab is a symlink. The first line of the start() function is: [ -L /etc/mtab ] && return 0 That should keep the warning from printing on systems where /etc/mtab is a symlink unless I'm missing something? I am closing this due to no response from the reporter and because I have checked the code in /etc/init.d/mtab. Once mtab is a symlink, it does not replace it. I think there is something more on the reporter's system which is rewriting mtab as a file. (In reply to William Hubbs from comment #6) > I am closing this due to no response from the reporter Response to what? I'm reporting that my symlink is deleted on boot. I don't see why this bug is invalid :-/ If any package in Gentoo deletes that file, it's a bug. And I don't have any software installed that runs at boot and isn't a portage package. So somewhere, there is a bug. Can you delete this line in the mtab init script: ln -snf /proc/self/mounts /etc/mtab and put an ewarn in its place so you'll know if it is doing it and then try rebooting? Also maybe `grep -Rn mtab /etc` and see if there is anything else referring to it? (In reply to Jason Zaman from comment #8) > Can you delete this line in the mtab init script: > > ln -snf /proc/self/mounts /etc/mtab Please don't; this will make the mtab init script create mtab as a file, which is what we do not want. > and put an ewarn in its place so you'll know if it is doing it and then try > rebooting? If you want to put an ewarn in the init script, put it above the line you were asked to delete. > > Also maybe `grep -Rn mtab /etc` and see if there is anything else referring > to it? I did not mark the bug invalid; it was marked "worksforme" which means that I tested openrc and found it doesn't do this. I wasn't saying that you don't have a bug, I was just saying I don't see the bug in OpenRC; it is in another package. Since this is more a support issue than a bug at this point, I recommend asking for help on the gentoo-user mailing list, the #gentoo irc channel on freenode, or the forums. OK. It seems Gentoo is not interested in finding out and fixing its own bugs. Good job. Nikos, Everyone who has looked at this report cannot reproduce this, you're gonna have to do some legwork on this one. It really does appear to be a local issue, not a bug in openrc. I'd suggest taking advantage of openrc's interactive RC mode and try dropping to a shell before and after the mtab service starts to see if you can pin down exactly when things go awry. Does /etc/mtab exist at all before the mtab service starts? Does it exist after, and is it a file or link? etc But detailed "try this, report back" over and over troubleshooting really is better suited for a support venue like IRC or forums, we'd be very happy to help there. I'm just trying to help. There's something wrong, not necessarily with openrc. Could be another package. It is a bug though. I don't need help myself. I'm creating the symlink in an /etc/local.d/ file. Problem solved. The bug is still there though. Your loss, I guess. If you are the only one experiencing a problem and you are not willing to investigate, by all reasonable measures, there is no bug. If you actually do want to solve this, we need you to help us, with some more information. If you have lost interest in the issue, fine... but it's not like no one is willing to help you. |
