Re: Permissions on /etc/sudoers messed up - reflash?
To wrap it up: Meego let me down, I finally reflashed. The problem was the ubifs used on the maemo root. Couldn't get it mounted in meego. Most of the backup-restore worked fine, a bunch of apps are missing. So, no way to access the rootfs without maemo; mission failed. -- Philipp Haselwarter ___ maemo-users mailing list maemo-users@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-users

Too bad. Furthermore I had a really hard time with the keyboard; the only keys I was able to use were [a-zA-Z<>], no dashes, no slashes (the modifier key seems to just get ignored). Maybe I could use the chmod on the rootfs? Still, if I can neither type "-w" nor "440" that's no use.

Hi! rootsh package does not modify root password, but openssh does.

The root password should be the one you created when you installed the rootsh package. If you forgot it, then... I have not tried it, but you might be able to use a rescue initrd like the one described here to gain access to your rootfs: http://wiki.meego.com/ARM/N900/Using_Rescue_Initrd There are also a few things that could have helped, had you installed them ahead of time, like backupmenu, or if you have NITdroid or MeeGo in a dual-boot environment you might be able to use them to edit your file permissions.

Sudoers
Ok, not finding the warnings until AFTER I screwed up, is there any way to repair /etc/sudoers without reflashing? In trying to run a program that required root, I "sudo gainroot" and ran the program; however, the program didn't run properly so I changed the permissions from 440 to 660 on sudoers, added an entry and all was good. EXCEPT I didn't change the permissions back. Duh. Now, of course, after logging out of root, I can't log back in as root and 'Application Manager' doesnt work. I'm prepared to flash but would rather not. I have a current backup but I have numerous programs and reloading them will be a royal pain. Thanks in advance for any suggestions/recommendations. Again, I'm prepared for the, "you're screwed, dude - reflash." Hopefully it won't come to that...
