Ben Grommes <ben.grommes@xxxxxxxxxxxxxxxxxx> spake thusly:
My kickstart script reads user input in the %pre scriptlet using
the read
command. This worked fine in CentOS 4.4, but in CentOS 4.5 it no
longer works.
It appears that the read command is not taking input from the
console.
I'm doing a headless mode install (text option in ks.cfg).
Here is my %pre script:
%pre
install="no"
while [ "$install" != "yes" ]; do (
echo -n "Proceed with install? "
)>/dev/tty1
read install
done
The output of the echo shows up on the screen, but the read
command doesn't
accept any input from the keyboard.
Any suggestions for how to debug this would be appreciated.
Try explicitly redirecting stdin as well:
%pre
install="no"
while [ "$install" != "yes" ]; do
( echo -n "Proceed with install? " ) >/dev/tty1 </dev/tty1
read install
done
This is a good suggestion, but based on the symptoms it's more likely
that stdin needs to be redirected to the read, rather than the echo.
What I would do is either use chvt to change vts and get rid of the
redirection entirely, or use exec to redirect for the entirety of the
script:
# Method 1 - chvt with no redirection
%pre
chvt 1
install="no"
while [ "$install" != "yes" ]; do
echo -n "Proceed with install?"
read install
done
chvt 3 # (or maybe 6, depending on the type of install you are doing)
# Method 2 - redirect the whole script
%pre
exec </dev/tty1 >/dev/tty1 2>/dev/tty1
install="no"
while [ "$install" != "yes" ]; do
echo -n "Proceed with install?"
read install
done
# Method 3 - wrap the redirection around the whole loop
%pre
(
install="no"
while [ "$install" != "yes" ]; do
echo -n "Proceed with install?"
read install
done
) < /dev/tty1 >/dev/tty1 2>/dev/tty1
