6. 7. Extending a Logical Volume 63

6. 6. Three Finger Salute

We want to be able to shutdown or reboot our machine from the text console by pressing <CTRL-ALT-DEL>

and <CTRL-ALT-INS>, respectively.Both can be conﬁgured in /etc/inittab, the former one directly,the latter one

by using the kbdrequest feature and deﬁning the key KeyboardSignal as <CTRL-ALT-INS> in the kernel

keymaps.

/etc/console/linux-kbdrequest.inc:

control alt keycode 110 = KeyboardSignal

Modiﬁcation of /etc/console/uk.kmap:

include "linux−kbdrequest"

Modiﬁcation of /etc/inittab:

#What to do when CTRL−ALT−DEL is pressed.

ca:12345:ctrlaltdel:/sbin/shutdown −t1 −a −h now

#Action on special keypress (CTRL−ALT−INS)

kb::kbrequest:/sbin/shutdown −t1 −a −r now

6. 7. Extending a Logical Volume

Sonner or later we will run out of space on our /home partition. No problem: Wejust extend the corresponding

Logical Volume. Doing so is extremely simple and easy.

Extending the Logical Volume /dev/disk/home:

#> umount /home

#> tune2fs −O ˆhas_journal

#> e2fsadm −L +10G /dev/disk/home

#> tune2fs −O has_journal

#> mount /home
