Bug 66021

Summary:	-current system mount is broken: mount: exec mount_ufs2 not found
Product:	Base System	Reporter:	dl <dl>
Component:	kern	Assignee:	bmilekic
Status:	Closed FIXED
Severity:	Affects Only Me
Priority:	Normal
Version:	5.2-CURRENT
Hardware:	Any
OS:	Any

Description dl 2004-04-27 10:40:14 UTC

After updating -CURRENT, I installed kernel and booted in single-user.
After seeding random and running mergemaster -p (as suggested by 
UPDATING), the system did not allow to remount / with the
error-message as above. 

However, root seems to be mounted read-write already, since 
I could run mergmaster and update the master.passwd.

I read the archives and stumbled across this error, and now I am
afraid to follow-through with the update, in case the system will
then be broken. The error-messages suggest that it is not impossible
to create an broken system, thus I did not yet installed world.
Especially the new "mount" binary in /usr/obj/usr/src/sbin/mount/
shows the same problem, and there is no 'mount_ufs2' binary anywhere
(of course not).

Fix: 

unknown.
How-To-Repeat: 
Update your -current to Tue Apr 27  09:59:27 CEST, build world and kernel,
install kernel, boot in single-user, try to remount /

Assign to Bosko, whose recent commit 
(http://docs.freebsd.org/cgi/getmsg.cgi?fetch=108969+0+current/cvs-all) 
is a large suspect here. 

Bosko, other users are reporting breakage of the form: 

# mount 
/dev/ad0s3a on / (ufs22, local) 
devfs on /dev (devfs, local) 
/dev/ad0s3e on /usr (ufs22, local, soft-updates) 
/dev/ad0s3f on /home (ufs22, local, soft-updates) 
/dev/ad0s3d on /var (ufs22, local, soft-updates) 
procfs on /proc (procfs, local)
