Hello,
Sorry, my previois message was truncated; here is the text, fully:
I tried to trace Zones booting with DTrace.
I ran DTrace thus:
dtrace -qn 'proc:::exec-success { printf("%-14s
%s\n",curthread->t_procp->p_parent->p_user.u_comm, curpsinfo->pr_psargs); }'
and from another terminal ran:
zoneadm -z myzone boot
what I got is:
tcsh zoneadm -z myzone boot
zoneadm zoneadmd -z myzone
zoneadmd mount -o attrdir=/export/home/myzone/dev /dev
/export/home/myzone/root/dev
zoneadmd mount -o ro,nosub,nodevices /lib /export/home/myzone/root/lib
zoneadmd mount -o ro,nosub,nodevices /platform
/export/home/myzone/root/platform
zoneadmd mount -o ro,nosub,nodevices /sbin /export/home/myzone/root/sbin
zoneadmd mount -o ro,nosub,nodevices /usr /export/home/myzone/root/usr
zoneadmd mount /opt/local /export/home/myzone/root/usr/local
zsched /sbin/init
init INITSH -c exec /lib/svc/bin/svc.startd >/dev/msglog
2<>/dev/msglog </dev/consol
init /lib/svc/bin/svc.startd
svc.startd /lib/svc/bin/svc.configd
svc.startd /sbin/sh -c exec /lib/svc/method/net-loopback
Now, I saw that in the "Solaris Internals" book there is the same dtrace script
example for booting a zone. But with some differences.
In the book example, after the last mount, there is a call to
"devfsadm -z demozone" while I do not have this at all.
My question is : as I understand, there is a single devfsadmd daemon
which runs on the global zone. Moreover , each zone was registered with this
devfsadmd daemon by a door IPC; there was a door in /dev/.zone_reg_door and
also in /dev/.devfsadm_synch_door. I do not have these doors under /dev in
"myzone".
My question is : was something changed in the zoneadmd and devfsadm
doors interaction? I want to add that I am running snv_54; I did not
find in the changelog anything about such a change, though.
(Another thing that I want to mention is that in the book example ,
root/dev is a mounted with zonedevfs option;
the first mount in the book is
"zoneadmd mount -o zonedevfs /zones/demozone/dev /zones/demozone/root/dev"
in my output it does not appear with the zonedevfs option.)
Regards,
Xu
