Having just done a 'make build' to move from a -current of around November
to -current as of 23 February (which completed successfully), I rebooted
(now running a recent -current), and did a 'make release' so I could have
good snapshot of a system.  (this is on port-i386)

The majority of the build took place on my /scratch partition, which is a
6+ gig LFS partition, about 20% full.

Somewhere during the install phase, I got the following panic:

[ installing merrily ] 

(cd etc.i386; install  -c -o root  -g wheel -m 444 fstab.* /scratch/build/etc)
(cd /scratch/build/dev; ./MAKEDEV all)
(cd ../usr.bin/mail; make distribution)
cd /scratch/src/usr.bin/mail/misc; install -c -o root -g wheel  -m 644 mail.rc /scratch/build/etc
(cd ../gnu/usr.sbin/sendmail/cf/cf; make distribution)
install -c -o root -g wheel -m 444  /scratch/build/etc/
/scratch/build/usr/libexec/sendmail/sendmail -C /scratch/build/etc/ -O AliasFile=/scratch/build/etc/aliases -bi

... at which point I rebooted.  If there's anything else I should do with
a panic of this nature, please let me know.
