Description

Hi,

tuxillo noticed that the trick to speedup booting by hitting <enter>
does not work with default UFS-based installations, as those have no
separate /boot partition, and therefore the default location for the
loader is wrong (it had been changed to match default HAMMER
installations in 3735e368a1bdbe773c79c34512f49c905ff77bd7)

We could change boot2 to just continue it's normal operation without
entering the prompt when the user hits <enter>. That way one can avoid
the delay on UFS and HAMMER systems:

diff --git a/sys/boot/pc32/boot2/boot2.c b/sys/boot/pc32/boot2/boot2.c
index 459436f..55516be 100644

     if (autoboot && !*kname) {
     memcpy(kname, PATH_BOOT3, sizeof(PATH_BOOT3));
-    if (!keyhit(3*SECOND)) {
+    if (!keyhit(3*SECOND) || xgetc(0) == '\r') {
         load();
         memcpy(kname, PATH_BOOT3_ALT, sizeof(PATH_BOOT3_ALT));
         load();


To actually enter the prompt one has to hit any other key (e.g. Esc).

The check for '\r' works ok for me, but maybe we also need to check
for '\n'?

Cheers,
Johannes

Johannes,

Is this still present? I see there was a commit related to this in
3735e368a1bdbe773c79c34512f49c905ff77bd7

That commit changed things, so on installations with dedicated /boot
partition the speed up by hitting return works ok.
However it no longer works on installations that don't have a /boot
partition.
The patch I proposed in msg8262 makes it work on both kinds of
installations, but it's sort of a hack.

Cheers,
Johannes

I've created a VM with a UFS installation and no dedicated /boot partition:

root@:~ # df -h /boot 
Filesystem     Size   Used  Avail Capacity  Mounted on
/dev/vbd0s1d  32.5G  1575M  28.3G     5q    /

I'm unable to reproduce this issue. Could it be that it happens only in some hardware because pressing the Enter key produces a different character?
