Top posting is discouraged on this list. |

Actually, I read your email several times. I found it lacking detail and |
43 |
substance and so I guessed for your problem. If you "boot livecd/usb to |
44 |
a network connection" and then run "mount /dev/sdc3 /mnt/gentoo" you |
45 |
should not receive "can't find /dev/sdc3 in /etc/fstab". Most reasonable |
46 |
explanation for that response is running "mount /dev/sdc3" from the |
47 |
livemedia which specifies the partition only and results in mount |
48 |
looking for mountpoint and options in /etc/fstab on the livemedia. The |
49 |
livemedia has no listing for /dev/sdc3 in /etc/fstab. |

|
51 |
example:(sda2 is not in my fstab) ~ # mount /dev/sda2 |
52 |
mount: can't find /dev/sda2 in /etc/fstab |
53 |
|
54 |
example: ~ # mount /mnt/gentoo |
55 |
mount: can't find /mnt/gentoo in /etc/fstab |
56 |
|
57 |
example: ~ # mount /dev/sda2 /mnt/gentoo |
58 |
~ # mount | grep -i sda2 |
59 |
/dev/sda2 on /mnt/gentoo type vfat |
60 |
(rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro) |
61 |
|
62 |
specifying device and mount point without information on either in fstab |
63 |
causes mount to probe for information and use defaults. |
