Great! Thank you. This works very well.
What I have done is putting only the directories in the var.cpio.gz,
as follows:
find /var -type d | cpio -o > /conf/base/var.cpio
gzip /conf/base/var.cpio
to regenerate the directory tree for /var on the diskless PC, assuming
that individual files will be created as the system boots.
The latter is indeed the case with files like
/var/run/dmesg.boot
/var/run/sshd.pid
/var/run/syslog.pid
/var/run/syslogd.sockets
and so forth.
However, /var/log/ is empty and remains empty !?!? Any idea why that is?
I need to inspect files like /var/log/auth.log, /var/log/messages and
so on. Why are these log files not generated?
syslogd is running:
# ps awux | grep syslog
root 231 0.0 2.7 1316 760 ?? Ss 6:20PM 0:00.13 /usr/sbin/syslogd -ss
rob 677 0.0 1.1 476 312 p2 R+ 8:09PM 0:00.01 grep syslog
Thanks!
Rob.
