I'm surprised by that. Google found similar error messages where a *user* could not do things because /dev itself had the wrong permissions (ls -ld /dev in chroot). But you should be root here in chroot, so perms for group and other are irrelevant. And you bound the host's /dev in 6.2.2, didn't you ? Oh, that must be it. I did section 6.2.2 but then I shut down my computer and later resumed. I'm sorry. I should have known that would be a problem. It doesn't preserve mounted stuff for the next terminal session. Anyway, I did that section again and it works now! Thank you very much! > which is correct. So that can't be the problem. The FAQ (http://www.linuxfromscratch.org/lfs/faq.html#perm-denied) also says it can be /etc/fstab. But I'm not sure which one. The one on the host system says: > > /dev/mapper/isw_bejfhacdjf_Volume1p4 / ext4 errors=remount-ro $ > /dev/mapper/isw_bejfhacdjf_Volume1p5 none swap sw 0 $ > /dev/mapper/isw_bejfhacdjf_Volume1p5 none swap sw 0 $ > I don't think /dev/mapper entries are the problem : if there is a problem in the host system's fstab, it probably relates to /dev itself. I say 'probably' because I'm not familiar with that entry in the FAQ and I don't recall anybody mentioning permission problems with /dev on the lists. > > I don't know if there is a problem there. On the LFS partition, /etc/fstab doesn't exist. Is that a problem? > No, not at this stage - you have barely started building the final LFS system. And since you didn't comment on my previous replies that /mnt/lfs should be its own filesystem, I still doubt that you will be able to boot your new system when you complete it. I hope I'm wrong on that. I'm building LFS in its own filesystem. For some reason my distro mounts filesystems in media/<username> hence /media/isaac/LFS. Isaac
