[Bug 236975] Re: WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed
I don't see why a separate 'export ROOTFLAGS' is necessary. init already exports ROOTFLAGS right up at the top, which is sufficient to export all later settings of it. If this doesn't work it's a shell bug, but one I can't reproduce in isolated testing on Intrepid. -- WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed https://bugs.launchpad.net/bugs/236975 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 236975] Re: WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed
Agostino points out that 'export ROOTFLAGS' was introduced in initramfs- tools in intrepid, so this was needed in hardy but is no longer needed in intrepid. -- WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed https://bugs.launchpad.net/bugs/236975 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 236975] Re: WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed
I think that Andrew is referring to a Hardy installation, where export ROOTFLAGS is required. This was corrected in Intrepid (0.92a), so there is no need for step 1 and 3 in 8.10. In intrepid, it should be sufficient to pass any required rootflags argument in menu.lst (step #2) and run update-grub. In hardy, follow Andrew's recipe above. -- WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed https://bugs.launchpad.net/bugs/236975 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 236975] Re: WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed
Thank you Andrew, these last instructions worked very well for me (I applied them on the 12 windows XP machines with WUBI 8.04 that i have in the computer lab of the school i work for as a teacher). Georgios Kolomvos Patras, Greece Andrew Flegg: A slightly neater way, rather than modifying root_locale is to add a new root_opts file: 1) Create /usr/share/initramfs-tools/conf.d/root_opts containing export ROOTFLAGS [ this is the root cause of step 2 not working alone] 2) Append rootflags=gid=115,fmask=113,dmask=002 to the end of the #kopt= line in /boot/grub/menu.lst 3) Run sudo update-initramfs -k all -u and sudo update-grub -- WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed https://bugs.launchpad.net/bugs/236975 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 236975] Re: WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed
Thank you for the update. If I'm not wrong, this would make it easier for end-users to tweak permissions if you don't put a password on the grub menu entries (which you should do anyway, as otherwise unprivileged users could be dropped to a root shell) I know it's a bit of security-through-obscurity and is certainly less flexible, but I think it might be safer to have the desired permissions hard-coded in the initramfs. Perhaps I'm worng/misguided. Wouldn't be the first time. Anyway, either way it does the job. It'd be just fantastic if there was a nice little GUI that would do this for you (or at least documentation, which I guess is what this is now.) Alas, I'm not volunteering to do it.

[Bug 236975] Re: WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed
Hello, I am now facing the same problem. In the related question (#35664) Agostino Russo mentioned: You might have to pass them as a kernel boot parameter in menu.lst via rootflags=YOURMOUNTOPTIONS Would it be possible for someone to provide a working an example of this? To be honest, I've looked in the usual places (mtab, fstab, menu.lst) and I can't see where /host is mounted. (When I say umount /host or mount -o remount /host the system says unmountable/unable to remount.) I would think that the loopback mount needs rw access to /host/ubuntu/disk/* but to make all files in /host 777 is maybe overkill...

[Bug 236975] Re: WUBI Ubuntu 8.04, access permissions on /host folder cannot be changed
The mounting for /host is done in the initramfs, which makes this tricky
(for me anyway) to track down. I've found a workaround for the problem:
Edit /usr/share/initramfs-tools/scripts/local-premount/root_locale
Append ,umask=022 to this line:
echo ROOTFLAGS=\${ROOTFLAGS}locale=$ROOT_LOCALE\
/conf/param.conf
so that it reads:
echo ROOTFLAGS=\${ROOTFLAGS}locale=$ROOT_LOCALE,umask=022\
/conf/param.conf
Save, run:
update-initramfs -k all -u
Reboot. /host will now be 755.
There may be a more appropriate place to make this change, but after
hours of googling and poking around various scripts, that worked for me.
