Re: Classic Gnubie accident
Hi there,
I don't have a problem getting at the files, booting single user or into a failsafe terminal as myself (username=anthony) the problem is exactly how to correctly 'check/fix owner/permissions until you are happy.'
I just need to know what ownership and permissions my /home/anthony folder should be set to and how to do this safely as root (I cannot access these files as myself (username=anthony). I.e. I need to know the exact commands
and how to check afterwards the permissions have been set correctly
thanks
Anthony

If booting in single-user mode doesn't work, boot into a shell.
I don't know what boot loader you're using but if you
haven't pre-configured a boot option that gives you a shell,
you need to note the whole kernel boot command line,
then reboot but when you get the boot prompt (lilo, grub, whatever),
enter your kernel boot command line and add init=/bin/sh (or dash if its
installed).
At this point nothing is mounted. Check the owner/permissions of the
/home mount point and fix as needed.
Then go to /etc/rcS.d and manually start each script in the order listed
with (for example on mine):
./S02mountvirtfs start
until /home is mounted, then you can descend the /home directory and
check/fix owner/permissions until you are happy.
Then you have to manually go through /etc/rc0.d and run the scripts
starting with (on mine)
./S40umountfs start (because it the first letter is 'S')
Then power off and try a single-mode boot. If that works, try a normal
boot.
Doug.
