Title:
run_scripts_optional sets 'y' value but call_scripts checks for
'optional' value

Bug description:
I looked into my initramfs and found there big graphics modules for hardware
which I don't have.
I found a place where these modules were copied into initramfs, it was in
/usr/share/initramfs-tools/hooks/framebuffer
Also I found a recipe on the Internet, advising to put 'FRAMEBUFFER=n' into
initramfs.conf to exclude optional hooks and scipts which have
OPTION=FRAMEBUFFER in them from initramfs creation
I tried to set this option and to update my initramfs, but did not succeed
So I examined mkinitramfs and related scripts and found this sequence in
/usr/share/initramfs-tools/hook-functions :
run_scripts_optional()
{
call_scripts_optional=y
run_scripts "$@"
}
...
run_scripts()
{
...
call_scripts $scriptdir
}
...
call_scripts()
{
...
for cs_x in ${runlist}; do
...
if [ x"$call_scripts_optional" = "xoptional" ]; then
option=$(sed
'/^OPTION=/!d;$d;s/^OPTION=//;s/[[:space:]]*$//' "${initdir}/${cs_x}")
[ -z "${option}" ] || eval test -n \"\${$option}\" -a
\"\${$option}\" != \"n\" || continue
fi
...
done
...
}
As you see, variable 'call_scripts_optional' is set to vaue 'y' in
run_scripts_optional function, but then it is checked for having
'optional' value in call_scripts function
This is observed at least in up-to-date Ubuntu Xenial and Zesty
I will also check equivalent scripts in Debian testing/unstable and report my
finding in a comment below.
