chroot "Permission denied"

jollyjoice · 02-05-2005, 02:01 PM

KK, trying to install gentoo 64 from inside fedora 3 (32) when i try and chroot it throws this at me, yes i am root yes it is 777d and yes it does the same with nano instead of bash.

Code:

[root@C0bra christopher]# chroot /media/gentoo64 /bin/bash
chroot: cannot run command `/bin/bash': Permission denied

any ideas?

Are you sure that the bash executable is in /bin and not /usr/bin or /usr/local/bin?

Do a whereis bash to find out where exactly it is.

[root@C0bra christopher]# whereis bash
bash: /bin/bash /usr/share/man/man1/bash.1.gz

I'm no expert with chroot, but doesn't chroot try to run the executable from within the new root? In other words, wouldn't a copy of bash need to be in /media/gentoo64/bin?

EDIT: I honestly don't know... so I'm asking as well as suggesting...

Well... it is, ls /media/gentoo64/bin lists bash as being there.

Dark_Hemlet... drrr, your totally right, god only knows what I was thinking....

Did you use the correct string of switches when you untared the stage file? Check the handbook but I'm sure you have to use -p and possibly some others.

yes i did, just gone thrugh the whole thing again.

I do believe you need to bind /proc and possibly /dev as shown in the alternative installation guide

mount -o bind /proc /mnt/gentoo/proc
and possibly mount -o bind /dev /mnt/gentoo/dev

still no luck, might go burn that ISO...

If you mount the intended filesystem with user option you will get this error... chrooted filesystems must be mounted root only.

I had the same problem. This fixed it for me (run as root):

# mount -o remount,dev,exec /chrootDirectory
